curl_setopt

(PHP 4 >= 4.0.2, PHP 5)

curl_setoptDéfinit une option de transmission cURL

Description

bool curl_setopt ( resource $ch , int $option , mixed $value )

curl_setopt() définit l'option de transfert cURL option, avec la valeur value pour la requête ch.

Liste de paramètres

ch

Un gestionnaire cURL retourné par la fonction curl_init().

option

L'option CURLOPT_XXX à définir.

value

La valeur à définir pour option.

value doit être un bool pour les valeurs suivantes du paramètre option :

Option Définissez le paramètre value à Notes
CURLOPT_AUTOREFERER TRUE pour spécifier automatiquement le champ Referer: dans les requêtes où une redirection Location: suit.
CURLOPT_BINARYTRANSFER TRUE pour retourner les données brutes (données binaires) lorsque CURLOPT_RETURNTRANSFER est utilisé. Depuis PHP 5.1.3, cette option n'a aucun effet : l'affichage brute sera toujours retourné lorsque l'option CURLOPT_RETURNTRANSFER est utilisé.
CURLOPT_COOKIESESSION TRUE pour marquer ceci comme un nouveau cookie "session". Cela forcera libcurl à ignorer tous les cookies qui sont prêts à être chargés qui sont des "cookies de session" provenant des sessions antérieures. Par défaut, libcurl enregistre et charge toujours tous les cookies, indépendamment s'ils sont des cookies de session ou pas. Les cookies de session sont des cookies sans date d'expiration et existeront que pour cette "session" seulement.
CURLOPT_CERTINFO TRUE pour sortir les informations de certification SSL vers STDERR pour les transferts sécurisés. Ajouté en cURL version 7.19.1. Disponible depuis PHP 5.3.2. Requiert CURLOPT_VERBOSE d'être activé.
CURLOPT_CONNECT_ONLY TRUE indique à la bibliothèque d'effectuer toutes les configurations nécessaires à l'authentification et la connexion au proxy, mais ne transfère aucune donnée. Cette option est implémentée pour HTTP, SMTP et POP3. Ajouté en cURL 7.15.2. Disponible depuis PHP 5.5.0.
CURLOPT_CRLF TRUE pour convertir les nouvelles lignes Unix en nouvelles lignes CRLF pendant le transfert.
CURLOPT_DNS_USE_GLOBAL_CACHE TRUE pour utiliser un cache DNS global. Cette option n'est pas compatible avec les threads et est activée par défaut.
CURLOPT_FAILONERROR TRUE pour que PHP traite, avec des traces, les codes HTTP supérieurs ou égaux à 400. Le comportement par défaut est de retourner la page normalement, en ignorant ce code.
CURLOPT_FILETIME TRUE pour tenter de récupérer la date de modification du document distant. Vous pouvez également retrouver cette valeur en utilisant l'option CURLINFO_FILETIME avec curl_getinfo().
CURLOPT_FOLLOWLOCATION TRUE pour suivre toutes les en-têtes "Location: " que le serveur envoie dans les en-têtes HTTP (notez que cette fonction est récursive et que PHP suivra toutes les en-têtes "Location: " qu'il trouvera à moins que CURLOPT_MAXREDIRS ne soit définie).
CURLOPT_FORBID_REUSE TRUE pour forcer la connexion à se fermer explicitement lorsque le processus est terminé et ne sera pas mise en cache pour être réutilisée.
CURLOPT_FRESH_CONNECT TRUE pour forcer à utiliser une nouvelle connexion au lieu de celle en cache.
CURLOPT_FTP_USE_EPRT TRUE pour utiliser EPRT (et LPRT) lors de l'activation des téléchargements FTP. Utilisez FALSE pour désactiver EPRT et LPRT et ainsi, n'utiliser que PORT.
CURLOPT_FTP_USE_EPSV TRUE pour tenter tout d'abord une commande EPSV pour les transferts FTP avant de revenir à une commande PASV. Définissez cette option à FALSE pour désactiver EPSV.
CURLOPT_FTP_CREATE_MISSING_DIRS TRUE pour créer les dossiers intermédiaires lorsqu'une opération FTP est demandée sur un chemin qui n'existe pas.
CURLOPT_FTPAPPEND TRUE pour que PHP ajoute les informations au fichier distant, plutôt que de l'écraser.
CURLOPT_TCP_NODELAY Spécifie si l'option TCP_NODELAY doit être définie ou non (1 = défini, 0 = non défini). L'option vaut 0 par défaut. Disponible depuis PHP 5.2.1 pour les versions compilées avec libcurl 7.11.2 ou supérieur.
CURLOPT_FTPASCII Un alias de CURLOPT_TRANSFERTEXT. Utilisez celui-là à la place.
CURLOPT_FTPLISTONLY TRUE pour ne lister que les noms d'un dossier FTP.
CURLOPT_HEADER TRUE pour inclure l'en-tête dans la valeur de retour.
CURLINFO_HEADER_OUT TRUE pour suivre la chaîne de requête handle. Disponible depuis PHP 5.1.3. Le préfixe CURLINFO_ est intentionnel.
CURLOPT_HTTPGET TRUE pour réinitialiser la méthode de requête HTTP à GET. Sachant que GET est la valeur par défaut, cela n'est uniquement nécessaire que si la méthode de requête a été changée.
CURLOPT_HTTPPROXYTUNNEL TRUE pour effectuer un tunnel à travers un proxy HTTP.
CURLOPT_MUTE TRUE pour que PHP soit totalement silencieux concernant toutes les fonctions cURL. Supprimé en cURL 7.15.5 (Vous pouvez utiliser CURLOPT_RETURNTRANSFER à la place)
CURLOPT_NETRC TRUE pour que PHP analyse votre fichier ~./netrc et utilise votre nom de compte et mot de passe sur le site distant que vous souhaitez contacter.
CURLOPT_NOBODY TRUE pour que le corps du transfert ne soit pas inclus dans la valeur de retour. La méthode de demande est définie à HEAD. Le fait de modifier cette option à la valeur FALSE ne modifie pas la méthode GET.
CURLOPT_NOPROGRESS

TRUE pour désactiver la barre de progression des transferts cURL.

Note:

PHP définit automatiquement cette option à TRUE. Ne changez cette valeur que le temps du déboguage.

CURLOPT_NOSIGNAL TRUE pour ignorer toutes les fonctions cURL qui cause l'envoi d'un signal au processus PHP. Activée par défaut dans les SAPI multithreadés, les options d'expiration peut toujours être utilisées. Ajouté dans cURL 7.10.
CURLOPT_POST TRUE pour que PHP fasse un HTTP POST. Un POST est un encodage normal application/x-www-from-urlencoded, utilisé couramment par les formulaires HTML.
CURLOPT_PUT TRUE pour que le chargement se fasse par HTTP PUT. Le fichier à charger doit être fixé avec les options CURLOPT_INFILE et CURLOPT_INFILESIZE.
CURLOPT_RETURNTRANSFER TRUE retourne directement le transfert sous forme de chaîne de la valeur retournée par curl_exec() au lieu de l'afficher directement.
CURLOPT_SAFE_UPLOAD TRUE désactive le support du préfixe @ pour l'envoi de fichiers dans CURLOPT_POSTFIELDS, ce qui signifie que les valeurs commençant avec @ peuvent être passées comme paramètres sans danger. CURLFile devrait être utilisé pour les envois de fichiers. Ajouté dans PHP 5.5.0 avec comme valeur par défaut, FALSE. PHP 5.6.0 modifie la valeur par défaut à TRUE.
CURLOPT_SSL_VERIFYPEER FALSE pour arrêter CURL de vérifier le certificat. Les certificats alternatifs peuvent être spécifiés avec l'option CURLOPT_CAINFO (ajouté dans CURL 7.9.8) ou un répertoire de certificat peut être spécifié avec l'option CURLOPT_CAPATH. TRUE par défaut depuis cURL 7.10. Paquet installé par défaut depuis cURL 7.10.
CURLOPT_TRANSFERTEXT TRUE pour utiliser le mode ASCII pour les transferts FTP. Pour LDAP, il récupère les données en texte plein au lieu d'HTML. Sur les systèmes Windows, STDOUT ne sera pas définie en mode binaire.
CURLOPT_UNRESTRICTED_AUTH TRUE pour garder l'envoi du nom de l'utilisateur ainsi que le mot de passe lorsque l'on suit les chemins (en utilisant CURLOPT_FOLLOWLOCATION), même si le nom d'hôte change.
CURLOPT_UPLOAD TRUE pour que PHP prépare un chargement.
CURLOPT_VERBOSE TRUE pour afficher tous les événements. Écrit la sortie sur STDERR ou dans le fichier spécifié en utilisant CURLOPT_STDERR.

value doit être un integer pour les valeurs suivantes du paramètres option :

Option Définissez le paramètre value à Notes
CURLOPT_BUFFERSIZE La taille du buffer à utiliser pour chaque lecture. Cependant, il n'y a aucune garantie que cette requête soit accomplie. Ajouté en cURL 7.10.
CURLOPT_CLOSEPOLICY Une des valeurs de CURLCLOSEPOLICY_*.

Note:

Cette option est obsolète, sachant qu'elle n'a jamais été implémenté en cURL, et n'a jamais eu aucun effet.

Supprimé en PHP 5.6.0.
CURLOPT_CONNECTTIMEOUT Le nombre de secondes à attendre durant la tentative de connexion. Utilisez 0 pour attendre indéfiniment.
CURLOPT_CONNECTTIMEOUT_MS Le nombre de millisecondes à entendre durant la tentative de connexion. Utilisez 0 pour attendre indéfiniment. Si libcurl est construit pour utiliser le système standard de résolution de noms, cette partie de la connexion utilisera toujours la seconde résolution pour le délai d'attente maximal avec un délai d'attente maximal minimum autorisé d'une seconde. Ajouté en cURL 7.16.2. Disponible depuis PHP 5.2.3.
CURLOPT_DNS_CACHE_TIMEOUT Le temps en seconde que CURL doit conserver les entrées DNS en mémoire. Cette option est définie à 120 secondes (2 minutes) par défaut.
CURLOPT_FTPSSLAUTH La méthode d'identification FTP, lorsqu'elle est activée : CURLFTPAUTH_SSL (tente SSL en premier), CURLFTPAUTH_TLS (tente TLS en premier) ou CURLFTPAUTH_DEFAULT (laisse cURL décider). Ajouté en cURL 7.12.2.
CURLOPT_HTTP_VERSION CURL_HTTP_VERSION_NONE (défaut, laisse cURL décider la version à utiliser), CURL_HTTP_VERSION_1_0 (force HTTP/1.0), ou CURL_HTTP_VERSION_1_1 (force HTTP/1.1).
CURLOPT_HTTPAUTH

La méthode d'identification HTTP à utiliser. Ces options sont : CURLAUTH_BASIC, CURLAUTH_DIGEST, CURLAUTH_GSSNEGOTIATE, CURLAUTH_NTLM, CURLAUTH_ANY et CURLAUTH_ANYSAFE.

Vous pouvez utiliser le séparateur | ou un opérateur pour combiner plus d'une méthode. Si vous faites cela, CURL interrogera le serveur pour voir quelles sont les méthodes supportées et prendra la meilleur.

CURLAUTH_ANY est un alias pour CURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM.

CURLAUTH_ANYSAFE est un alias pour CURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM.

CURLOPT_INFILESIZE La taille attendue, en octets, du fichier lors du téléchargement d'un fichier depuis un site distant. Notez que l'utilisation de cette option n'arrêtera pas libcurl d'envoyer de plus de données, de la même façon que ce qui est envoyé dépend de l'option CURLOPT_READFUNCTION.
CURLOPT_LOW_SPEED_LIMIT La vitesse de transfert minimale en octets par secondes en dessous de laquelle, et pendant CURLOPT_LOW_SPEED_TIME secondes, PHP considérera qu'elle est trop lente, et annulera le transfert.
CURLOPT_LOW_SPEED_TIME Le temps en secondes, pendant lequel si le transfert reste en dessous de CURLOPT_LOW_SPEED_LIMIT, PHP considérera que la connexion est trop lente, et l'annulera.
CURLOPT_MAXCONNECTS Le nombre maximal de connexions persistantes autorisées. Lorsque la limite est atteinte, l'option CURLOPT_CLOSEPOLICY est utilisé pour afficher les connexions fermées.
CURLOPT_MAXREDIRS Le nombre maximal de redirections HTTP à suivre. Utilisez cette option avec l'option CURLOPT_FOLLOWLOCATION.
CURLOPT_PORT Le numéro du port de connexion, à la place de la valeur par défaut utilisée par le protocole.
CURLOPT_PROTOCOLS

Champ de bits de valeurs CURLPROTO_*. S'il est utilisé, ce champ limite les protocoles qui peuvent être utilisés durant un transfert. Cela vous permet de limiter le nombre de protocoles utilisés par la libcurl, tout en la compilant avec un grand nombre d'entre eux. Par défaut, libcurl va accepter tous les protocoles qu'elle supporte. Voyez aussi CURLOPT_REDIR_PROTOCOLS.

Les options valides de protocoles sont : CURLPROTO_HTTP, CURLPROTO_HTTPS, CURLPROTO_FTP, CURLPROTO_FTPS, CURLPROTO_SCP, CURLPROTO_SFTP, CURLPROTO_TELNET, CURLPROTO_LDAP, CURLPROTO_LDAPS, CURLPROTO_DICT, CURLPROTO_FILE, CURLPROTO_TFTP, CURLPROTO_ALL

Ajouté en cURL 7.19.4.
CURLOPT_PROXYAUTH La méthode d'identification HTTP à utiliser pour la connexion à un proxy. Utilisez la même méthode que celle décrite dans CURLOPT_HTTPAUTH. Pour une identification avec un proxy, seuls CURLAUTH_BASIC et CURLAUTH_NTLM sont actuellement supportés. Ajouté en CURL 7.10.7.
CURLOPT_PROXYPORT Le numéro du port du proxy à utiliser pour la connexion. Ce numéro de port peut également être défini dans l'option CURLOPT_PROXY.
CURLOPT_PROXYTYPE Soit CURLPROXY_HTTP (par défaut), soit CURLPROXY_SOCKS5. Ajouté en cURL 7.10.
CURLOPT_REDIR_PROTOCOLS Champ de bits de constantes CURLPROTO_*. S'il est utilisé, ce champ limite les protocoles que libcurl peut utiliser pour un transfert, après une redirection lorsque CURLOPT_FOLLOWLOCATION est actif. Cela permet de spécifier une sous-partie des protocoles compilés avec libcurl. Par défaut, libcurl va autoriser tous les protocoles, hormis FILE et SCP. C'est une différence importante avec les versions précédents la 7.19.4, qui suivaient inconditionnellement tous les protocoles supportés. Voyez aussi CURLOPT_PROTOCOLS pour connaître la liste des valeurs des constantes. Ajoutés en cURL 7.19.4.
CURLOPT_RESUME_FROM L'offset, en octets, à partir duquel vous voulez commencer le transfert.
CURLOPT_SSL_VERIFYHOST 1 pour vérifier l'existence d'un nom commun dans le certificat SSL. 2 pour vérifier l'existence d'un nom commun et vérifier qu'il correspond avec le nom d'hôte fourni. En environnement de production, la valeur de cette option doit être conservée à 2 (valeur par défaut). Support pour la valeur 1 supprimé en cURL 7.28.1
CURLOPT_SSLVERSION La version de SSL (2 ou 3) à utiliser. Par défaut, PHP essayera de le déterminer lui-même, bien que dans certains cas, il vous faudra le faire manuellement.
CURLOPT_TIMECONDITION Comment CURLOPT_TIMEVALUE est traité. Utilisez CURL_TIMECOND_IFMODSINCE pour retourner la page uniquement si elle a été modifiée depuis le temps spécifié par CURLOPT_TIMEVALUE. Si elle n'a pas été modifiée, un en-tête HTTP "304 Not Modified" sera retourné en supposant que CURLOPT_HEADER vaut TRUE. Utilisez CURL_TIMECOND_IFUNMODSINCE pour faire l'inverse. CURL_TIMECOND_IFMODSINCE est par défaut.
CURLOPT_TIMEOUT Le temps maximum d'exécution de la fonction cURL.
CURLOPT_TIMEOUT_MS Le nombre maximal de millisecondes autorisé aux fonctions cURL pour l'exécution. Si libcurl est construit pour utiliser le système standard de résolution de noms, cette partie de la connexion utilisera toujours la seconde résolution pour le délai d'attente maximal avec un délai d'attente maximal minimum autorisé d'une seconde. Ajouté en cURL 7.16.2. Disponible depuis PHP 5.2.3.
CURLOPT_TIMEVALUE Le temps en secondes depuis le 1er janvier 1970. Cette valeur sera utilisée comme spécifié dans l'option CURLOPT_TIMECONDITION. Par défaut, CURL_TIMECOND_IFMODSINCE sera utilisée.
CURLOPT_MAX_RECV_SPEED_LARGE Si un téléchargement en réception excède cette vitesse (comptée en octets par seconde) sur une moyenne cumulée durant le transfert, le transfert se mettra en pause pour conserver la moyenne inférieure ou égales à la valeur de ce paramètre. Par défaut, la vitesse est illimitée. Ajouté en cURL 7.15.5. Disponible depuis PHP 5.4.0.
CURLOPT_MAX_SEND_SPEED_LARGE Si un téléchargement en émission excède cette vitesse (comptée en octets par seconde) sur une moyenne cumulée durant le transfert, le transfert se mettra en pause pour conserver la moyenne inférieure ou égales à la valeur de ce paramètre. Par défaut, la vitesse est illimitée. Ajouté en cURL 7.15.5. Disponible depuis PHP 5.4.0.
CURLOPT_SSH_AUTH_TYPES Un masque constitué d'une ou plusieurs constantes suivantes : CURLSSH_AUTH_PUBLICKEY, CURLSSH_AUTH_PASSWORD, CURLSSH_AUTH_HOST, CURLSSH_AUTH_KEYBOARD. Utilisez la constante CURLSSH_AUTH_ANY pour laisser libcurl en choisir une pour vous. Ajouté en cURL 7.16.1.
CURLOPT_IPRESOLVE Autorise une application à sélectionner le type d'adresse IP à utiliser lors de la résolution des noms d'hôtes. Ceci n'est intéressant que lors de l'utilisation des noms d'hôtes qui résolvent les adresses en utilisant plus d'une version d'IP ; les valeurs possibles sont CURL_IPRESOLVE_WHATEVER, CURL_IPRESOLVE_V4, CURL_IPRESOLVE_V6 ; par défaut, vaut CURL_IPRESOLVE_WHATEVER. Ajouté en cURL 7.10.8.

value doit être une chaîne pour les valeurs suivantes du paramètres option :

Option Définissez le paramètre value à Notes
CURLOPT_CAINFO Le nom d'un fichier contenant un ou plusieurs certificats pour vérifier la concordance. Cela n'a de sens que si vous l'utilisez en combinaison de l'option CURLOPT_SSL_VERIFYPEER. Nécessite un chemin absolu.
CURLOPT_CAPATH Un dossier qui contient les certificats. Utilisez cette option avec l'option CURLOPT_SSL_VERIFYPEER.
CURLOPT_COOKIE Le contenu de l'en-tête "Cookie: ", à transmettre dans l'en-tête HTTP. Notez que les cookies sont séparées par des points-virgule, suivi d'un d'espace (e.g., "fruit=pomme; couleur=rouge")
CURLOPT_COOKIEFILE Le nom du fichier contenant les données de cookie. Le fichier de cookie peut être au format Netscape, ou simplement des en-têtes HTTP écrits dans un fichier. Si le nom est une chaîne de caractère vide, aucun cookie n'est chargé, mais le gestionnaire est toujours actif.
CURLOPT_COOKIEJAR Le nom de fichier pour y sauvegarder tous les cookies internes lorsque la connexion se ferme, par exemple après un appel à curl_close.
CURLOPT_CUSTOMREQUEST

Une méthode de requête qui sera utilisée à la place de "GET" ou "HEAD" lors des requêtes HTTP. Cette commande est pratique pour effectuer un "DELETE" ou une autre commande HTTP exotique. Les valeurs valides sont "GET", "POST", "CONNECT" et plus ; i.e. n'entrez pas une requête HTTP ici. Pour le moment, entrez "GET /index.html HTTP/1.0\r\n\r\n" serait incorrect.

Note:

N'utilisez pas cette commande sans vous assurer que le serveur l'accepte.

CURLOPT_EGDSOCKET Comme CURLOPT_RANDOM_FILE excepté que vous passez une chaîne qui contient un nom de fichier vers le socket Entropy Gathering Daemon.
CURLOPT_ENCODING Le contenu des en-têtes "Accept-Encoding: " et active le décodage de la réponse. Les encodages supportés sont "identity", "deflate" et "gzip". Si une chaîne vide "" est utilisé, un en-tête contenant tous les types d'encodage supportés est envoyé. Ajouté en cURL 7.10.
CURLOPT_FTPPORT La valeur qui sera utilisée pour récupérer l'adresse IP utilisée pour l'instruction FTP "PORT". L'instruction PORT indique au serveur distant de se connecter à cette adresse IP. La chaîne peut être une adresse IP, un nom d'hôte, un nom d'interface réseau (sous UNIX), ou juste '-', pour utiliser les IP par défaut du système.
CURLOPT_INTERFACE Le nom de l'interface à utiliser. Cela peut être le nom d'une interface, une adresse IP ou encore le nom de l'hôte.
CURLOPT_KEYPASSWD Le mot de passé nécessaire pour utiliser la clé privée CURLOPT_SSLKEY ou la clé privée CURLOPT_SSH_PRIVATE_KEYFILE. Added in cURL 7.16.1.
CURLOPT_KRB4LEVEL Le degré de sécurité KRB4 (Kerberos 4). Chacune des valeurs (dans l'ordre du plus petit au plus grand) suivantes sont valides : "clear", "safe", "confidential", "private".. Si la chaîne passée ne correspond pas à une de ces valeurs, la valeur "private" sera définie. Positionner cette valeur à NULL revient à désactiver la sécurité KRB4. Actuellement, la sécurité KRB4 fonctionne uniquement avec les transaction FTP.
CURLOPT_POSTFIELDS Toutes les données à passer lors d'une opération de HTTP POST. Pour envoyer un fichier, préfixez le nom du fichier avec un @ et utilisez le chemin complet. Le type de fichier peut être explicitement spécifié en faisant suivre le nom du fichier par le type au format ';type=mimetype'. Ce paramètre peut être passé sous la forme d'une chaîne encodée URL, comme 'para1=val1&para2=val2&...' ou sous la forme d'un tableau dont le nom du champ est la clé, et les données du champ la valeur. Si le paramètre value est un tableau, l'en-tête Content-Type sera définie à multipart/form-data. Depuis PHP 5.2.0, value doit être un tableau si les fichiers sont passés à cette option avec le préfixe @. Depuis PHP 5.5.0, le préfixe @ est obsolète et les fichiers peuvent être envoyés en utilisant CURLFile. Le préfixe @ peut être désactivé, pour passer sans danger des valeurs commençant par @, en définissant l'option CURLOPT_SAFE_UPLOAD à TRUE.
CURLOPT_PROXY Le nom du proxy HTTP au tunnel qui le demande.
CURLOPT_PROXYUSERPWD Un nom d'utilisateur et un mot de passe formatés sous la forme "[username]:[password]" à utiliser pour la connexion avec le proxy.
CURLOPT_RANDOM_FILE Un nom de fichier à utiliser pour interroger le générateur de nombre aléatoire pour SSL.
CURLOPT_RANGE La plage de valeurs à récupérer sous la forme "X-Y", où les valeurs de X ou Y peuvent être omises. Le transfert HTTP supporte aussi plusieurs intervalles, séparés par des virgules : "X-Y,N-M".
CURLOPT_REFERER Le contenu de l'en-tête "Referer: " à utiliser dans une requête HTTP.
CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 Une chaîne contenant 32 digits hexédécimaux. La chaîne doit être la somme MD5 de la clé publique de l'hôte distant, et libcurl rejètera la connexion à l'hôte tant que les sommes MD5 ne corresponderont pas. Cette option n'est valable que pour les transferts SCP et SFTP. Ajouté en cURL 7.17.1.
CURLOPT_SSH_PUBLIC_KEYFILE Le nom du fichier pour la clé publique. Si non utilisé, libcurl utilisera pas défaut $HOME/.ssh/id_dsa.pub si la variable d'environnement $HOME est définie, et seulement "id_dsa.pub" si HOME n'est pas définie. Ajouté en cURL 7.16.1.
CURLOPT_SSH_PRIVATE_KEYFILE Le nom du fichier pour la clé privée. Si non utilisé, libcurl utilisera pas défaut $HOME/.ssh/id_dsa si la variable d'environnement $HOME est définie, et seulement "id_dsa" si HOME n'est pas définie. Si le fichier est protégé par un mot de passe, définissez le avec la constante CURLOPT_KEYPASSWD. Ajouté en cURL 7.16.1.
CURLOPT_SSL_CIPHER_LIST Une liste de chiffrements à utiliser avec SSL. Par exemple, RC4-SHA et TLSv1 sont des listes valides de chiffrements.
CURLOPT_SSLCERT Le nom de fichier du certificat, au format PEM.
CURLOPT_SSLCERTPASSWD Le mot de passe nécessaire pour utiliser le certificat CURLOPT_SSLCERT.
CURLOPT_SSLCERTTYPE Le format de votre certificat. Les formats supportés sont "PEM" (par défaut), "DER", et "ENG". Ajouté en cURL 7.9.3.
CURLOPT_SSLENGINE L'identifiant pour le moteur de chiffrement de votre clé privée spécifié dans CURLOPT_SSLKEY.
CURLOPT_SSLENGINE_DEFAULT L'identifiant pour le moteur de chiffrement utilisé pour les opérations de chiffrement asymétrique.
CURLOPT_SSLKEY Un nom de fichier contenant votre clé privée SSL.
CURLOPT_SSLKEYPASSWD

Le mot de passe secret utilisé par votre clé SSL privée spécifié dans CURLOPT_SSLKEY.

Note:

Du fait que cette option contient un mot de passe sensible, souvenez-vous de conserver le script PHP qui le contient en toute sécurité.

CURLOPT_SSLKEYTYPE Le type de votre clé SSL privée spécifié dans CURLOPT_SSLKEY. Les types de clé supportés sont "PEM" (par défaut), "DER", et "ENG".
CURLOPT_URL L'URL à récupérer. Vous pouvez aussi choisir cette valeur lors de l'appel à curl_init().
CURLOPT_USERAGENT Le contenu de l'en-tête "User-Agent: " à utiliser dans une requête HTTP.
CURLOPT_USERPWD Un nom d'utilisateur et un mot de passe formatés sous la forme "[username]:[password]" à utiliser pour la connexion.

value doit être un tableau pour les valeurs suivantes du paramètres option :

Option Définissez le paramètre value à Notes
CURLOPT_HTTP200ALIASES Un tableau de réponses HTTP 200 qui sera traité comme réponses valides et non comme des erreurs. Ajouté en CURL 7.10.3.
CURLOPT_HTTPHEADER Un tableau de champs d'en-têtes HTTP à définir, au format array('Content-type: text/plain', 'Content-length: 100')
CURLOPT_POSTQUOTE Un tableau de commandes FTP à exécuter sur le serveur après que la requête FTP se soit exécutée.
CURLOPT_QUOTE Un tableau de commandes FTP à exécuter sur le serveur avant la requête FTP.

value doit être une ressource (utilisant fopen(), par exemple) pour les valeurs suivantes du paramètre option :

Option Définissez le paramètre value à
CURLOPT_FILE Le fichier où sera écrit le transfert. Par défaut, STDOUT (la fenêtre du navigateur).
CURLOPT_INFILE Le fichier lu par le transfert lors du chargement.
CURLOPT_STDERR Un chemin alternatif à utiliser pour afficher les erreurs au lieu de STDERR.
CURLOPT_WRITEHEADER Le fichier où sera écrit les parties d'en-tête du transfert.

value doit être le nom d'une fonction ou d'une Closure valide pour les valeurs suivantes du paramètres option :

Option Définissez le paramètre value à
CURLOPT_HEADERFUNCTION Une fonction de rappel acceptant deux paramètres. Le premier est la ressource cURL, le second, une chaîne de caractères avec les données d'en-têtes à écrire. Ces données d'en-têtes doivent être écrites par cette fonction de rappel. Le nombre d'octets écrit sera retourné.
CURLOPT_PASSWDFUNCTION Une fonction de rappel qui prend trois paramètres. Le premier est la ressource CURL, le second, une chaîne contenant un mot de passe de prompt et le troisième, est la longueur maximale du mot de passe. Retourne une chaîne contenant le mot de passe.
CURLOPT_PROGRESSFUNCTION

Une fonction de rappel qui prend cinq arguments. Le premier est la ressource cURL, le second est le nombre total d'octets attendu à télécharger pendant le transfert, le troisième est le nombre d'octets téléchargés, le quatrième est le total d'octets attendu à uploader pendant le transfert, et le cinqquième est le nombre d'octets uploadés.

Note:

The callback is only called when the CURLOPT_NOPROGRESS option is set to FALSE.

Return a non-zero value to abort the transfer. In which case, the transfer will set a CURLE_ABORTED_BY_CALLBACK error.

CURLOPT_READFUNCTION Une fonction de rappel qui prend trois paramètres. Le premier est une ressource cURL, le second, une ressource de flux fournie à cURL via l'option CURLOPT_INFILE, et le troisième, la quantité maximale de données à lire. La fonction de rappel doit retourner une chaîne dont la taille est inférieure ou égale à la quantité de données demandées, habituellement en les lisant depuis la ressource de flux passée. Elle doit retourner une chaîne vide pour signaler la fin EOF.
CURLOPT_WRITEFUNCTION Une fonction de rappel qui prend deux paramètres. Le premier est la ressource CURL et le second, une chaîne contenant les données à écrire. En utilisant cette fonction de rappel, il devient de votre responsabilité d'écrire les données. Doit retourner le nombre exact d'octets écrits ou le transfert échouera avec une erreur.

Autres valeurs :

Option Définit le paramètre value en
CURLOPT_SHARE Un résultat de la fonction curl_share_init(). Fait que le gestionnaire cURL va utiliser les données depuis le gestionnaire partagé.

Valeurs de retour

Cette fonction retourne TRUE en cas de succès ou FALSE si une erreur survient.

Exemples

Exemple #1 Initialisation d'une nouvelle session CURL et recherche d'une page Web

<?php
// Création d'une ressource cURL
$ch curl_init();

// Définition de l'URL et autres options appropriées
curl_setopt($chCURLOPT_URL"http://www.example.com/");
curl_setopt($chCURLOPT_HEADERfalse);

// Récupération de l'URL et passage au navigateur
curl_exec($ch);

// Fermeture de la ressource cURL et libération des ressources systèmes
curl_close($ch);
?>

Exemple #2 Télécharger un fichier sur un serveur

<?php

/* http://localhost/upload.php:
print_r($_POST);
print_r($_FILES);
*/

$ch curl_init();

$data = array('name' => 'Foo''file' => '@/home/user/test.png');

curl_setopt($chCURLOPT_URL'http://localhost/upload.php');
curl_setopt($chCURLOPT_POST1);
curl_setopt($chCURLOPT_POSTFIELDS$data);

curl_exec($ch);
?>

L'exemple ci-dessus va afficher :

Array
(
    [name] => Foo
)
Array
(
    [file] => Array
        (
            [name] => test.png
            [type] => image/png
            [tmp_name] => /tmp/phpcpjNeQ
            [error] => 0
            [size] => 279
        )

)

Notes

Note:

Le fait de passer un tableau à la constante CURLOPT_POSTFIELDS encodera les données comme multipart/form-data, tandis que le fait de passer une chaîne encodée URL encodera les données comme application/x-www-form-urlencoded.

Please everyone, stop setting CURLOPT_SSL_VERIFYPEER to false or 0. If your PHP installation doesn't have an up-to-date CA root certificate bundle, download the one at the curl website and save it on your server:

http://curl.haxx.se/docs/caextract.html

Then set a path to it in your php.ini file, e.g. on Windows:

curl.cainfo=c:\php\cacert.pem

Turning off CURLOPT_SSL_VERIFYPEER allows man in the middle (MITM) attacks, which you don't want!

Clarification on the callback methods:

- CURLOPT_HEADERFUNCTION is for handling header lines received *in the response*,
- CURLOPT_WRITEFUNCTION is for handling data received *from the response*,
- CURLOPT_READFUNCTION is for handling data passed along *in the request*.

The callback "string" can be any callable function, that includes the array(&$obj, 'someMethodName') format.

It appears that setting CURLOPT_FILE before setting CURLOPT_RETURNTRANSFER doesn't work, presumably because CURLOPT_FILE depends on CURLOPT_RETURNTRANSFER being set.

So do this:

<?php
curl_setopt
($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $fp);
?>

not this:

<?php
curl_setopt
($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
?>

PUT requests are very simple, just make sure to specify a content-length header and set post fields as a string.

Example:

<?php
function doPut($url, $fields)
{
  
$fields = (is_array($fields)) ? http_build_query($fields) : $fields;

   if(
$ch = curl_init($url))
   {
     
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
     
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
     
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($fields)));
     
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
     
curl_exec($ch);

     
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);

     
curl_close($ch);

      return (int)
$status;
   }
   else
   {
      return
false;
   }
}

if(
doPut('http://example.com/api/a/b/c', array('foo' => 'bar')) == 200)
  
// do something
else
  
// do something else.
?>

You can grab the request data on the other side with:

<?php
if($_SERVER['REQUEST_METHOD'] == 'PUT')
{
  
parse_str(file_get_contents('php://input'), $requestData);

  
// Array ( [foo] => bar )
  
print_r($requestData);

  
// Do something with data...
}
?>

DELETE  can be done in exactly the same way.

After much struggling, I managed to get a SOAP request requiring HTTP authentication to work.  Here's some source that will hopefully be useful to others.

         <?php

         $credentials
= "username:password";
        
        
// Read the XML to send to the Web Service
        
$request_file = "./SampleRequest.xml";
       
$fh = fopen($request_file, 'r');
       
$xml_data = fread($fh, filesize($request_file));
       
fclose($fh);
               
       
$url = "http://www.example.com/services/calculation";
       
$page = "/services/calculation";
       
$headers = array(
           
"POST ".$page." HTTP/1.0",
           
"Content-type: text/xml;charset=\"utf-8\"",
           
"Accept: text/xml",
           
"Cache-Control: no-cache",
           
"Pragma: no-cache",
           
"SOAPAction: \"run\"",
           
"Content-length: ".strlen($xml_data),
           
"Authorization: Basic " . base64_encode($credentials)
        );
      
       
$ch = curl_init();
       
curl_setopt($ch, CURLOPT_URL,$url);
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
       
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
       
curl_setopt($ch, CURLOPT_USERAGENT, $defined_vars['HTTP_USER_AGENT']);
       
       
// Apply the XML to our curl call
       
curl_setopt($ch, CURLOPT_POST, 1);
       
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);

       
$data = curl_exec($ch);

        if (
curl_errno($ch)) {
            print
"Error: " . curl_error($ch);
        } else {
           
// Show me the result
           
var_dump($data);

I spent a couple of days trying to POST a multi-dimensional array of form fields, including a file upload, to a remote server to update a product. Here are the breakthroughs that FINALLY allowed the script to run as desired.

Firstly, the HTML form used input names like these:
<input type="text" name="product[name]" />
<input type="text" name="product[cost]" />
<input type="file" name="product[thumbnail]" />
in conjunction with two other form inputs not part of the product array
<input type="text" name="method" value="put" />
<input type="text" name="mode" />

I used several cURL options, but the only two (other than URL) that mattered were:
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $postfields);
Pretty standard so far.
Note: headers didn't need to be set, cURL automatically sets headers (like content-type: multipart/form-data; content-length...) when you pass an array into CURLOPT_POSTFIELDS.
Note: even though this is supposed to be a PUT command through an HTTP POST form, no special PUT options needed to be passed natively through cURL. Options such as
curl_setopt($handle, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT', 'Content-Length: ' . strlen($fields)));
or
curl_setopt($handle, CURLOPT_PUT, true);
or
curl_setopt($handle, CURLOPT_CUSTOMREQUEST, "PUT);
were not needed to make the code work.

The fields I wanted to pass through cURL were arranged into an array something like this:
$postfields = array("method" => $_POST["method"],
                    "mode" => $_POST["mode"],
                    "product" => array("name" => $_POST["product"],
                                        "cost" => $_POST["product"]["cost"],
                                        "thumbnail" => "@{$_FILES["thumbnail"]["tmp_name"]};type={$_FILES["thumbnail"]["type"]}")
                    );

-Notice how the @ precedes the temporary filename, this creates a link so PHP will upload/transfer an actual file instead of just the file name, which would happen if the @ isn't included.
-Notice how I forcefully set the mime-type of the file to upload. I was having issues where images filetypes were defaulting to octet-stream instead of image/png or image/jpeg or whatever the type of the selected image.

I then tried passing $postfields straight into curl_setopt($this->handle, CURLOPT_POSTFIELDS, $postfields); but it didn't work.
I tried using http_build_query($postfields); but that didn't work properly either.
In both cases either the file wouldn't be treated as an actual file and the form data wasn't being sent properly. The problem was HTTP's methods of transmitting arrays. While PHP and other languages can figure out how to handle arrays passed via forms, HTTP isn't quite as sofisticated. I had to rewrite the $postfields array like so:
$postfields = array("method" => $_POST["method"],
                    "mode" => $_POST["mode"],
                    "product[name]" => $_POST["product"],
                    "product[cost]" => $_POST["product"]["cost"],
                    "product[thumbnail]" => "@{$_FILES["thumbnail"]["tmp_name"]}");
curl_setopt($handle, CURLOPT_POSTFIELDS, $postfields);

This, without the use of http_build_query, solved all of my problems. Now the receiving host outputs both $_POST and $_FILES vars correctly.

Note that CURLOPT_RETURNTRANSFER when used with CURLOPT_WRITEFUNCTION has effectively three settings: default, true, and false.

default - callbacks will be called as expected.
true - content will be returned but callback function will not be called.
false - content will be output and callback function will not be called.

Note that CURLOPT_HEADERFUNCTION callbacks are always called.

When CURLOPT_FOLLOWLOCATION and CURLOPT_HEADER are both true and redirect/s have happened then the header returned by curl_exec() will contain all the headers in the redirect chain in the order they were encountered.

I've found that setting CURLOPT_HTTPHEADER more than once will clear out any headers you've set previously with CURLOPT_HTTPHEADER.

Consider the following:
<?php
   
# ...

   
curl_setopt($cURL,CURLOPT_HTTPHEADER,array (
       
"Content-Type: text/xml; charset=utf-8",
       
"Expect: 100-continue"
   
));

   
# ... do some other stuff ...

   
curl_setopt($cURL,CURLOPT_HTTPHEADER,array (
       
"Accept: application/json"
   
));

   
# ...
?>

Both the Content-Type and Expect I set will not be in the outgoing headers, but Accept will.

If you want to Curl to follow redirects and you would also like Curl to echo back any cookies that are set in the process, use this:

<?php curl_setopt($ch, CURLOPT_COOKIEJAR, '-'); ?>

'-' means stdout

If you wish to find the size of the file you are streaming and use it as your header this is how:

<?php

function write_function($curl_resource, $string)
{
    if(
curl_getinfo($curl_resource, CURLINFO_SIZE_DOWNLOAD) <= 2000)
    {
       
header('Expires: 0');
       
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
       
header('Pragma: public');
       
header('Content-Description: File Transfer');
       
header("Content-Transfer-Encoding: binary");
       
header("Content-Type: ".curl_getinfo($curl_resource, CURLINFO_CONTENT_TYPE)."");
       
header("Content-Length: ".curl_getinfo($curl_resource, CURLINFO_CONTENT_LENGTH_DOWNLOAD)."");
    }
   
    print
$string;

    return
mb_strlen($string, '8bit');
}

?>

1440 is the the default number of bytes curl will call the write function (BUFFERSIZE does not affect this, i actually think you can not change this value), so it means the headers are going to be set only one time.

write_function must return the exact number of bytes of the string, so you can return a value with mb_strlen.

If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/"feature"  on "Unix-like systems" that causes libcurl to timeout immediately if the value is < 1000 ms with the error "cURL Error (28): Timeout was reached".  The explanation for this behavior is:

"If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second."

What this means to PHP developers is "You can use this function without testing it first, because you can't tell if libcurl is using the standard system name resolver (but you can be pretty sure it is)"

The problem is that on (Li|U)nix, when libcurl uses the standard name resolver, a SIGALRM is raised during name resolution which libcurl thinks is the timeout alarm.

The solution is to disable signals using CURLOPT_NOSIGNAL.  Here's an example script that requests itself causing a 10-second delay so you can test timeouts:

<?php
if (!isset($_GET['foo'])) {
       
// Client
       
$ch = curl_init('http://localhost/test/test_timeout.php?foo=bar');
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
       
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
       
$data = curl_exec($ch);
       
$curl_errno = curl_errno($ch);
       
$curl_error = curl_error($ch);
       
curl_close($ch);

        if (
$curl_errno > 0) {
                echo
"cURL Error ($curl_errno): $curl_error\n";
        } else {
                echo
"Data received: $data\n";
        }
} else {
       
// Server
       
sleep(10);
        echo
"Done.";
}

Passing in PHP's $_SESSION into your cURL call:

<?php
session_start
();
$strCookie = 'PHPSESSID=' . $_COOKIE['PHPSESSID'] . '; path=/';
session_write_close();

$curl_handle = curl_init('enter_external_url_here');
curl_setopt( $curl_handle, CURLOPT_COOKIE, $strCookie );
curl_exec($curl_handle);
curl_close($curl_handle);
?>

This worked great for me.  I was calling pages from the same server and needed to keep the $_SESSION variables.  This passes them over.  If you want to test, just print_r($_SESSION);

Enjoy!

Handling redirections with curl if safe_mode or open_basedir is enabled. The function working transparent, no problem with header and returntransfer options. You can handle the max redirection with the optional second argument (the function is set the variable to zero if max redirection exceeded).
Second parameter values:
- maxredirect is null or not set: redirect maximum five time, after raise PHP warning
- maxredirect is greather then zero: no raiser error, but parameter variable set to zero
- maxredirect is less or equal zero: no follow redirections

<?php
function curl_exec_follow(/*resource*/ $ch, /*int*/ &$maxredirect = null) {
   
$mr = $maxredirect === null ? 5 : intval($maxredirect);
    if (
ini_get('open_basedir') == '' && ini_get('safe_mode' == 'Off')) {

curl_setopt($ch, CURLOPT_MAXREDIRS, $mr);
    } else {
       
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
        if (
$mr > 0) {
           
$newurl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

           
$rch = curl_copy_handle($ch);
           
curl_setopt($rch, CURLOPT_HEADER, true);

Many hosters use PHP safe_mode or/and open_basedir, so you can't use CURLOPT_FOLLOWLOCATION. If you try, you see message like this:
CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in [you script name & path] on line XXX

First, I try to use zsalab function (http://us2.php.net/manual/en/function.curl-setopt.php#102121) from this page, but for some reason it did not work properly. So, I wrote my own.

It can be use instead of curl_exec. If server HTTP response codes is 30x, function will forward the request as long as the response is not different from 30x (for example, 200 Ok). Also you can use POST.

function curlExec(/* Array */$curlOptions='', /* Array */$curlHeaders='', /* Array */$postFields='')
{
  $newUrl = '';
  $maxRedirection = 10;
  do
  {
    if ($maxRedirection<1) die('Error: reached the limit of redirections');

    $ch = curl_init();
    if (!empty($curlOptions)) curl_setopt_array($ch, $curlOptions);
    if (!empty($curlHeaders)) curl_setopt($ch, CURLOPT_HTTPHEADER, $curlHeaders);
    if (!empty($postFields))
    {
      curl_setopt($ch, CURLOPT_POST, 1);
      curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
    }
   
    if (!empty($newUrl)) curl_setopt($ch, CURLOPT_URL, $newUrl); // redirect needed
   
    $curlResult = curl_exec($ch);
    $code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    if ($code == 301 || $code == 302 || $code == 303 || $code == 307)
    {
      preg_match('/Location:(.*?)\n/', $curlResult, $matches);
      $newUrl = trim(array_pop($matches));
      curl_close($ch);

      $maxRedirection--;
      continue;
    }
    else // no more redirection
    {
      $code = 0;
      curl_close($ch);
    }
  }
  while($code);
  return $curlResult;

If you are trying to update something on your server and you need to handle this update operation by PUT;

<?php
curl_setopt
($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_PUT, 1);
?>

are "useless" without;

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT'));
?>

Example;

Updating a book data in database identified by "id 1";

--cURL Part--
<?php
$data
= http_build_query($_POST);
// or
$data = http_build_query(array(
  
'name'  => 'PHP in Action',
  
'price' => 10.9
));

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://api.localhost/rest/books/1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // no need anymore
// or
// curl_setopt($ch, CURLOPT_PUT, 1); // no need anymore
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$ce = curl_exec($ch);
curl_close($ch);
print_r($ce);
?>

--API class--
<?php
public function putAction() {
    echo
"putAction() -> id: ". $this->_getParam('id') ."\n";
   
print_r($_POST);
   
// do stuff with post data
   
...
?>

--Output--
putAction() -> id: 15

(
    [name] => PHP in Action
    [price] => 10.9
)

I noted something when using CURLOPT_POSTFIELDS in combination with arrays from PHP.

You may supply an array, but there may not be any sub-arrays in this array, as this will give Array-to-string-conversion notice.

Example:

<?php
$ch
= curl_init();

# this works
$data = array('name' => 'value');

# this gives "Notice: Array to string conversion..."
$data = array('name' => array('subname' => 'subvalue'));

curl_setopt($ch, CURLOPT_URL, 'http://localhost/test.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_exec($ch);
?>

if you need to send a SOAP string that is the CURL you must use :

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, XML_POST_URL);
curl_setopt ($ch, CURLOPT_HTTPHEADER, array('SOAPAction: ""'));   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POSTFIELDS, XML_PAYLOAD);
curl_setopt($ch, CURLOPT_HEADER, 0);

$output = curl_exec($ch);
?>

Note : Having based my snipet on Chemo demonstration (oscommerce user know who he is), XML_POST_URL and XML_PAYLOAD where defined as constant with define().

The point is : at the opposite of .xml , SOAP must send the header 'SOAPAction: ""' that can be a valid URI, an empty string (that is here) or nothing ('SOAPAction: '). The later case baing not accepted by all server, the second one indicating the target is the URI used to post the SOAP.

To find what encoding a given HTTP POST request uses is easy -- passing an array to CURLOPT_POSTFIELDS results in  multipart/form-data:

<?php
curl_setopt
(CURLOPT_POSTFIELDS, array('field1' => 'value'));
?>

Passing a URL-encoded string will result in application/x-www-form-urlencoded:

<?php
curl_setopt
(CURLOPT_POSTFIELDS, array('field1=value&field2=value2'));
?>

I ran across this when integrating with both a warehouse system and an email system; neither would accept multipart/form-data, but both happily accepted application/x-www-form-urlencoded.

This is very clear in hindsight, but it still cost me several hours:

<?php curl_setopt($session, CURLOPT_HTTPPROXYTUNNEL, 1); ?>

means that you will tunnel THROUGH the proxy, as in "your communications will go as if the proxy is NOT THERE".

Why do you care? - Well, if you are trying to use, say, Paros, to debug HTTP between your cURL and the server, with CURLOPT_HTTPPROXYTUNNEL set to TRUE Paros will not see or log your traffic thus defeating the purpose and driving you nuts.

There are other cases, of course, where this option is extremely useful...

If you are trying to use CURLOPT_FOLLOWLOCATION and you get this warning:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set...

then you will want to read http://www.php.net/ChangeLog-4.php which says "Disabled CURLOPT_FOLLOWLOCATION in curl when open_basedir or safe_mode are enabled." as of PHP 4.4.4/5.1.5.  This is due to the fact that curl is not part of PHP and doesn't know the values of open_basedir or safe_mode, so you could comprimise your webserver operating in safe_mode by redirecting (using header('Location: ...')) to "file://" urls, which curl would have gladly retrieved.

Until the curl extension is changed in PHP or curl (if it ever will) to deal with "Location:" headers, here is a far from perfect remake of the curl_exec function that I am using.

Since there's no curl_getopt function equivalent, you'll have to tweak the function to make it work for your specific use.  As it is here, it returns the body of the response and not the header.  It also doesn't deal with redirection urls with username and passwords in them.

<?php

if you would like to send xml request to a server (lets say, making a soap proxy),
you have to set

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml"));
?>

makesure you watch for cache issue:
the below code will prevent cache...

<?php
curl_setopt
($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);
?>

hope it helps ;)

The examples below for HTTP file upload work great, but I wanted to be able to post multiple files through HTTP upload using HTML arrays as specified in example 38.3 at

http://php.net/features.file-upload

In this case, you need to set the arrays AND keys in the $post_data, it will not work with just the array names. The following example shows how this works:

<?php

    $post_data
= array();
   
   
$post_data['pictures[0]'] = "@cat.jpg";
   
$post_data['pictures[1]'] = "@dog.jpg";
   

   
$ch = curl_init();
   
curl_setopt($ch, CURLOPT_URL, "http://example.com/my_url.php" );
   
curl_setopt($ch, CURLOPT_POST, 1 );
   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
$postResult = curl_exec($ch);

    if (
curl_errno($ch)) {
       print
curl_error($ch);
    }
   
curl_close($ch);
    print
"$postResult";
?>

To further expand upon use of CURLOPT_CAPATH and CURLOPT_CAINFO...

In my case I wanted to prevent curl from talking to any HTTPS server except my own using a self signed certificate. To do this, you'll need openssl installed and access to the HTTPS Server Certificate (server.crt by default on apache)

You can then use a command simiar to this to translate your apache certificate into one that curl likes.

$ openssl x509 -in server.crt -out outcert.pem -text

Then set CURLOPT_CAINFO equal to the the full path to outcert.pem and turn on CURLOPT_SSL_VERIFYPEER.

If you want to use the CURLOPT_CAPATH option, you should create a directory for all the valid certificates you have created, then use the c_rehash script that is included with openssl to "prepare" the directory.

If you dont use the c_rehash utility, curl will ignore any file in the directory you set.

I've been stuck when using the CURLOPT_CONNECTTIMEOUT_MS constant. In fact, on my PHP version (5.3.1) it's not a number but rather a string. Same thing for CURLOPT_TIMEOUT_MS.

I got this error: Warning: curl_setopt() expects parameter 2 to be long, string given

If you are experiencing simular problems, you can replace the constant with the actual number or (re)define the constant.

CURLOPT_TIMEOUT_MS should be 155
CURLOPT_CONNECTTIMEOUT_MS should be 156

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT_MS, 2500); // error
curl_setopt($ch, 156, 2500); // problem solved

If you need to send deta in a DELETE request, use:

<?php
$request_body
= 'some data';
$ch = curl_init('http://www.example.com');
       
curl_setopt($ch, CURLOPT_POSTFIELDS, $request_body);
       
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
       
curl_setopt($ch, CURLOPT_HEADER, 0);
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
       
$response = curl_exec($ch);
var_dump($response);

if you want to do a GET request with additional body data it will become tricky not to implicitly change the request to a POST, like many notes below correctly state.
So to do the analogy of command line's

curl -XGET 'http://example.org?foo=bar' -d '<baz>some additional data</baz>'

in PHP you'll do, besides your other necessary stuff,

<?php
    curl_setopt
($curlHandle, CURLOPT_CUSTOMREQUEST, 'GET');
   
curl_setopt($curlHandle, CURLOPT_POSTFIELDS, '<baz>some additional data</baz>');
?>

during my experiments, every other "similar" way, like e.g. CURLOPT_HTTPGET, didn't send the additional data or fell into POST.

If you are doing a POST, and the content length is 1,025 or greater, then curl exploits a feature of http 1.1: 100 (Continue) Status.

See http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.2.3

* it adds a header, "Expect: 100-continue". 
* it then sends the request head, waits for a 100 response code, then sends the content

Not all web servers support this though.  Various errors are returned depending on the server.  If this happens to you, suppress the "Expect" header with this command:

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, array('Expect:'));
?>

See http://www.gnegg.ch/2007/02/the-return-of-except-100-continue/

CURLOPT_POST must be left unset if you want the Content-Type header set to "multipart/form-data" (e.g., when CURLOPT_POSTFIELDS is an array). If you set CURLOPT_POSTFIELDS to an array and have CURLOPT_POST set to TRUE, Content-Length will be -1 and most sane servers will reject the request. If you set CURLOPT_POSTFIELDS to an array and have CURLOPT_POST set to FALSE, cURL will send a GET request.

Sometimes you can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE becoz of the server php-settings(They say u may grab any files from server using these options). Here is the solution
1)Don't use CURLOPT_FOLLOWLOCATION
2)Use curl_setopt($ch, CURLOPT_HEADER, 1)
3)Grab from the header cookies like this:
preg_match_all('|Set-Cookie: (.*);|U', $content, $results);   
$cookies = implode(';', $results[1]);
4)Set them using curl_setopt($ch, CURLOPT_COOKIE,  $cookies);

Good Luck, Yevgen

Be careful when changing CURLOPT_SSL_VERIFYHOST or other options to true (boolean). It may cause insecure behavior [1]

This is because boolean true casts into integer 1, and CURLOPT_SSL_VERIFYHOST = 1 is not secure behavior.

The *correct* value here is CURLOPT_SSL_VERIFYHOST = 2. By setting this value equal to 1 the peer certificate must contain a Common Name field, but it doesn't matter what name it says.

This may be not obvious, but if you specify the CURLOPT_POSTFIELDS and don't specify the CURLOPT_POST - it will still send POST, not GET (as you might think - since GET is default).
So the line:

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

is synonym to:

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

Even if you set the options like this (in this order):

curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

it will send POST, since CURLOPT_POSTFIELDS is latter.
So if you want GET - make sure you don't have CURLOPT_POSTFIELDS specified somewhere.

Force Curl Request To Go To A Particular IP Address

Yes, there is a method of passing an IP address to curl.  Excellent for services with multiple IP addresses and also to take DNS out of the equation for testing/debugging.

<?php
   
function fetch_page($url, $host_ip = NULL)
    {

     
$ch = curl_init();

      if (!
is_null($host_ip))
      {
       
$urldata = parse_url($url);

       
//  Ensure we have the query too, if there is any...
       
if (!empty($urldata['query']))
         
$urldata['path'] .= "?".$urldata['query'];

       
//  Specify the host (name) we want to fetch...
       
$headers = array("Host: ".$urldata['host']);
       
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

       
//  create the connecting url (with the hostname replaced by IP)
       
$url = $urldata['scheme']."://".$host_ip.$urldata['path'];
      }

     
curl_setopt($chCURLOPT_URL, $url);
     
curl_setopt ($ch, CURLOPT_HEADER, 0);
     
curl_setopt($chCURLOPT_RETURNTRANSFER, true);

     
$result = curl_exec ($ch);
     
curl_close ($ch);

$result;

Clarification for the CURLOPT_NOBODY option: by excluding the body from your request, you're effectively making a HEAD request. Use the CURLOPT_NOBODY option to return only the headers in the remote response.

Example:

<?php
function check_url($url) {
   
$c = curl_init();
   
curl_setopt($c, CURLOPT_URL, $url);
   
curl_setopt($c, CURLOPT_HEADER, 1); // get the header
   
curl_setopt($c, CURLOPT_NOBODY, 1); // and *only* get the header
   
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); // get the response as a string from curl_exec(), rather than echoing it
   
curl_setopt($c, CURLOPT_FRESH_CONNECT, 1); // don't use a cached version of the url
   
if (!curl_exec($c)) { return false; }

   
$httpcode = curl_getinfo($c, CURLINFO_HTTP_CODE);
    return (
$httpcode < 400);
}
?>

FYI,

Anyone trying to connect to .NET with CURL to send a simple XML post, pay attention to the following. This will save you hours! There is a previous note that I saw either on this page, or somewhere else on this site that explains the correct way to specify the header option is to create an array, then reference the array from the CURLOPT.

ie.  Do something like this:

<?php
// Req. HTTP Header Values
$header[] = "Content-type: text/xml";

// Target URL
$sendTo = "http://www.example.com";

// Post Data
$post = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<root>\n....etc, etc,";

// Create CURL Connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, 'XtraDoh xAgent');
curl_setopt($ch, CURLOPT_URL, $sendTo);
curl_setopt($ch, CURLOPT_TIMEOUT, 900);
curl_setopt($ch, CURLOPT_CONNECTIONTIMEOUT, 30);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
?>

Notice the HTTPHEADER, $header above. I have not been able to get .NET to properly read the HTTP header as specified (in this case as text/xml) when using the following:

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, array('Content-Type'=>'text/xml'));
?>

Although this may work when working with other PHP, IIS, or even PHP, Apache, it does not (at least in my experience) work with .NET, IIS.

Resetting CURLOPT_FILE to STDOUT won't work by calling curl_setopt() with the STDOUT constant or a php://output stream handle (at least I get error messages when trying the code from phpnet at andywaite dot com). Instead, one can simply reset it as a side effect of CURLOPT_RETURNTRANSFER. Just say

<?php curl_setopt($this->curl,CURLOPT_RETURNTRANSFER,0); ?>

and following calls to curl_exec() will output to STDOUT again.

If you have a mixture of strings starting with @ (at character) and files in CURLOPT_POSTFIELDS you have a problem (such as posting a tweet with attached media) because curl tries to interpret anything starting with @ as a file.

<?php

$postfields
= array(
   
'upload_file' => '@file_to_upload.png',
   
'upload_text' => '@text_to_upload'
);

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://example.com/upload-test');
curl_setopt($curl, CURLOPT_POSTFIELDS, $postfields);
curl_exec($curl);
curl_close($curl);

?>

To get around this, prepend the text string with the NULL character like so:

<?php
    $postfields
= array(
       
'upload_file' => '@file_to_upload.png',
       
'upload_text' => sprintf("\0%s", '@text_to_upload')
    );
?>

Hello.
During problems with "CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set"
I was looking for solution.
I've found few methods on this page, but none of them was good enough, so I made one.
<?php
function curl_redirect_exec($ch, &$redirects, $curlopt_header = false) {
   
curl_setopt($ch, CURLOPT_HEADER, true);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   
$data = curl_exec($ch);
   
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if (
$http_code == 301 || $http_code == 302) {
        list(
$header) = explode("\r\n\r\n", $data, 2);
       
$matches = array();
       
preg_match('/(Location:|URI:)(.*?)\n/', $header, $matches);
       
$url = trim(array_pop($matches));
       
$url_parsed = parse_url($url);
        if (isset(
$url_parsed)) {
           
curl_setopt($ch, CURLOPT_URL, $url);
           
$redirects++;
            return
curl_redirect_exec($ch, $redirects);
        }
    }
    if (
$curlopt_header)
        return
$data;
    else {
        list(,
$body) = explode("\r\n\r\n", $data, 2);
        return
$body;
    }
}
?>

Main issue in existing functions was lack of information, how many redirects was done.
This one will count it.
First parameter as usual.
Second should be already initialized integer, it will be incremented by number of done redirects.
You can set CURLOPT_HEADER if You need it.

When using CURLOPT_POSTFIELDS with an array as parameter, you have to pay high attention to user input. Unvalidated user input will lead to serious security issues.

<?php

/**
* test.php:
*/
$ch = curl_init('http://example.com');

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
   
'foo' => $_GET['bar']
));

curl_exec($ch);

?>

Requesting "test.php?bar=@/home/user/test.png" will send "test.png" to example.com.
Make sure you remove the leading "@" from user input.

I spent a couple of days trying to upload a file using a curl post.

The problem I ran into was the filename had an '@' in the middle of it.  It turned out that at least on my system if I encoded the file path using the quoted_printable_encode() function the upload works.

I'm posting this in the hopes that it will help someone else, and for my own future reference.

Code:
<?php

$filepath
= '/tmp/test@example.txt';
$postdata['file'] = '@' . quoted_printable_encode($filepath);

//... supporting code.

$result = curl_exec($ch);

?>
I'm not exactly sure why this works when escaping the '@' doesn't work but it does for me.

If anyone can offer insight into why this works or a better way to handle the '@' symbol in a filename when using curl to upload I would love to hear it.

Thanks

curl_setopt($curl, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($curl, CURLOPT_COOKIEJAR, "cookiefile"); # SAME cookiefile
curl_setopt($curl, CURLOPT_URL, "url1"); # this is where you first time connect - GET method authorization in my case, if you have POST - need to edit code a bit
$xxx = curl_exec($curl);

Remember:

- 'Server-side' cookies exists as information even before they were set on browser agent(HTTP COOKIE HEADER),
- javascript cookies does NOT exists as information before they were set on browser agent,

so, if you're trying to save cookies using CURLOPT_COOKIEJAR to a local file, that cookie must be server - side cookie, otherwise you are wasting time, javascript-produced cookies only exists when client browser's JS interpreter set them.

// do your progress stuff here
}

$ch = curl_init('http://www.example.com');

// This is required to curl give us some progress
// if this is not set to false the progress function never
// gets called
curl_setopt($ch, CURLOPT_NOPROGRESS, false);

// Set up the callback
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'callback');

// Big buffer less progress info/callbacks
// Small buffer more progress info/callbacks
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);

$data = curl_exec($ch);

beware that not all cURLlib constants are supported under php :
e.g. CURLOPT_PROGRESSFUNCTION or CURLOPT_WRITEDATA are not supported.

CURLOPT_WRITEFUNCTION, although undocumented is supported. It takes the name of a user_defined function.
the function should take two arguments (the curl handle, and the inputdata) and return the length of the written data
e.g.

<?php
function myPoorProgressFunc($ch,$str){
global
$fd;
$len = fwrite($fd,$str);
print(
"#");
return
$len;
}

curl_setopt($ch,CURLOPT_WRITEFUNCTION,"myPoorProgressFunc");
?>

Also be aware that CURLOPT_WRITEFUNCTION  does NOT take the CURLOPT_FILE as a parameter!
in curl lib it would take CURLOPT_WRITEDATA but this is not supported by php; that's why I use "global $fd;" in my exemple function.

CURLOPT_HEADERFUNCTION works the same, and is guaranteed to receive complete header lines as input!

Hope this helps

If you want to connect to a secure server for posting info/reading info, you need to make cURL with the openSSL options. Then the sequence is nearly identical to the previous example (except http_S_://, and possibly add the useragent):

<?php
curl_setopt
($ch, CURLOPT_URL,"https://example.com");
//some sites only accept your request if your browser looks legit, so send a useragent profile...
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");

if you use
<?php
curl_setopt
($ch, CURLOPT_INTERFACE, "XXX.XXX.XXX.XXX");
?>
to specify IP adress for request, sometimes you need to get list of all your IP's.

ifconfig command will output something like:

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=8<VLAN_MTU>
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX

tun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
    Opened by PID 565
    Opened by PID 565

My solution for FreeBSD 6 and PHP 5 was:
<?php
  ob_start
();
 
$ips=array();
 
$ifconfig=system("ifconfig");
  echo
$ifconfig;
 
$ifconfig=ob_get_contents();
 
ob_end_clean();
 
$ifconfig=explode(chr(10), $ifconfig);
  for (
$i=0; $i<count($ifconfig); $i++) {
   
$t=explode(" ", $ifconfig[$i]);
    if (
$t[0]=="\tinet") {
     
array_push($ips, $t[1]);
    }    
  }
  for (
$i=0; $i<count($ips); $i++) {
    echo
$ips[$i]."\n";
  }
?>

You will get list of IP adresses in $ips array, like:
82.146.XXX.XXX
78.24.XXX.XXX

Hi,
Anyone who is interested in submitting their information by post to HTTPS site (e.g. payment gateway) where https page needs basic authentication before submitting the information. below code will be helpful.

<?php
$submit_url
= "https://sitename/process.php";

$curl = curl_init();

curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC ) ;
curl_setopt($curl, CURLOPT_USERPWD, "username:password");
curl_setopt($curl, CURLOPT_SSLVERSION,3);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $params );
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($curl, CURLOPT_URL, $submit_url);

$data = split("text/html", curl_exec($curl) );
$temp = split("\r\n", $data[1]) ;

$result = unserialize( $temp[2] ) ;

print_r($result);
curl_close($curl);

Note that if you put a certificate chain in a PEM file, the certificates need to be ordered so that each certificate is followed by its issuer (i.e., root last.)

If you are using curl to do a soap request and consistently get the following error back:
The server cannot service the request because the media type is unsupported.
You are sending the Content-type of soap 1.2 to a 1.1 server.
Soap 1.1 needs Content-Type: text/xml;
Soap 1.2 should have Content-Type: application/soap+xml;

Make sure to set keys for array if passing to CURLOPT_POSTFIELDS.

<?php
//This can cause errors
$data = array('bar');

//Use this instead
$data = array('foo' => 'bar');

curl_setopt(CURLOPT_POSTFIELDS, $data);
?>

If your POST data seems to be disappearing (POST data empty, request is being handled by the server as a GET), try rearranging the order of CURLOPT_POSTFIELDS setting with CURLOPT_NOBODY. CURLOPT_POSTFIELDS has to come AFTER CURLOPT_NOBODY setting because if it comes after it wipes out the Content-Type header that tells your URL target that the request is a POST not a GET.

Not sure if this is expected behavior but it certainly isn't documented (except on Stackoverflow.com, which is supremely unhelpful - BTW, guys over on stack overflow... once you've figured out a PHP problem, posting the solution here would save everyone extra search time).

A note on the way Curl posts files...

<?php
  curl_setopt
($ch, CURLOPT_POSTFIELDS, array('file' => '@/path/to/file.ext');
?>

will post the FULL PATH of the file in the filename field:

Content-Disposition: form-data; name="file"; filename="/path/to/file.ext"

Whereas typical browser behavior only sends the filename:

Content-Disposition: form-data; name="file"; filename="file.ext"

Workaround:
<?php
  curl_setopt
($ch, CURLOPT_POSTFIELDS, array('file' => '@file.ext');
 
$cwd = getcwd();
 
chdir('/path/to/');
 
$receivedData = curl_exec($ch);
 
chdir($cwd);
?>

Be careful when setting the CURLOPT_POSTFIELDS setting using an array. The array used to set the POST fields must only contain scalar values. Multidimentional arrays or objects lacking a __toString implementation will cause Curl to error.

If there is a need to send non-scalar values using a POST request, consider serializing them before transmission.

<?php
$ch
= curl_init('http://host.example.com');

// Data to post
$multiDimensional = array(
  
'name' = 'foo',
  
'data' = array(1,2,3,4),
  
'value' = 'bar'
);

// Will error
curl_setopt($ch, CURLOPT_POSTFIELDS, $multiDimensional);

// Data to post
$postData = array(
 
'name' = 'foo',
 
'data' = serialize(array(1,2,3,4)),
 
'value' = 'bar'
);

// Will not error
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
?>

If you only want to enable cookie handling and you don't need to save the cookies for a separate session, just set CURLOPT_COOKIEFILE to an empty string.  I was given the advice to use php://memory but that did not seem to have the same effect.

Although this is stated in the documentation I thought it was worth reiterating since it cause me so much trouble.

If you get a "failed creating formpost data" upon curl_exec() when POSTing a form, check if one of the field values starts with the @ character.

Took me an hour or so to find out as I wanted to post a @reply tweet to twitter which typically start with @screenname.

Sometimes we want to extract the HTML content of the remote website page, this technique is called as HTML scrapper. This article will discuss on how we can extract the HTML content of the remote webpage.
We can achieve HTML scrapper operation in 2 step operation:
Call to Remote Web Page and extract the HTML content.
Match the HTML tags using Regular Expression.
Call to Remote Web Page using PHP:
In PHP there are various ways we can call the remote webpage. But here we will be using CURL to achieve our operation.

<?php
$ch

$timeout = 5; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

When you set ($ch, curlopt_post, 1) , after you have posted your data with curl_exec , you need to set ($ch, curlopt_post, 0), Otherwise all your subsequent requests seems as a post with no postdata and some reverse proxy servers send 500 or 403 error for these case ( access denied or forbidden )!

FYI... unless you specifically set the user agent, no user agent will be sent in your request as there is no default value like some of the other options.

As others have said, not sending a user agent may cause you to not  get the results that you expected, e.g., 0 byte length content, different content, etc.

If you use cURL to fetch user-supplied URLs (for instance, in a web-based RSS aggregator), be aware of the risk of server-side request forgery (SSRF). This is an attack where the user takes advantage of the fact that cURL requests are sent from the web server itself, to reach network locations they wouldn't be able to reach from outside the network.

For instance, they could enter a "http://localhost" URL, and access things on the web server via "localhost". Or, "ftp://localhost". cURL supports a lot of protocols!

If you are using CURLOPT_FOLLOWLOCATION, the malicious URL could be in a redirect from the original request. cURL also will follow redirect headers to other protocols! (303 See Other; Location: ftp://localhost).

So if you're using cURL with user-supplied URLs, at the very least use CURLOPT_PROTOCOLS (which also sets CURLOPT_REDIR_PROTOCOLS), and either disable CURLOPT_FOLLOWLOCATION or use the "SafeCurl" library to safely follow redirects.

When POSTing with cURL, my POSTs were magically being converted to GETs and I debugged it until finding the issue. I was setting the CURLOPT_MUTE option. Not sure why this conflicts, since the documentation doesn't specify as such. Anyways, if your $_POST is empty, make sure you aren't setting CURLOPT_MUTE.

Cheers!

to complement shiplu's  comment on the neccessary option sequence of CURLOPT_POST before CURLOPT_POSTFIELDS:

The crux is not some error on nginx, but that nothing at all will be send over the line by curl. Parameters set by a "CURLOPT_POSTFIELDS" option setting will be completely ignored, as long as no "CURLOPT_POST" has been encountered beforehand: Neigther the Content-Type header will be set/generated accordingly nor Content-Length nor any data will be send in the body.

When using curl_setopt_array, the sequence in the array matters as well.

One note of importance when you open several cURL handles simultaneously: If you want to share cookies via cookie-jar file among all your handles - be sure to curl_close() one before using the cookie-jar file from the other.

It appears that during cURL handler execution the cookies are kept in some sort of handler specific internal session storage and only upon explicit curl_close() call or interpreter exit garbage collection these cookies are actually flushed to the file on the hard disk ( I guess for performance reasons ).

I hope this note will save you couple of hours debugging :)

Some additional notes for curlopt_writefunction. I struggled with this at first because it really isn't documented very well.

When you write a callback function and use it with curlopt_writefunction it will be called MULTIPLE times. Your function MUST return the ammount of data written to it each time. It is very picky about this. Here is a snippet from my code that may help you

<?php
curl_setopt
($this->curl_handle, CURLOPT_WRITEFUNCTION, array($this, "receiveResponse"));

// later on in the class I wrote my receive Response method

private function receiveResponse($curlHandle,$xmldata)
                {
                       
$this->responseString = $xmldata;
                       
$this->responseXML .=  $this->responseString;
                       
$this->length = strlen($xmldata);
                       
$this->size += $this->length;
                        return
$this->length;

                }
?>

Now I did this for a class. If you aren't doing OOP then you will obviously need to modify this for your own use.

CURL calls your script MULTIPLE times because the data will not always be sent all at once. Were talking internet here so its broken up into packets. You need to take your data and concatenate it all together until it is all written. I was about to pull my damn hair out because I would get broken chunks of XML back from the server and at random lengths. I finally figured out what was going on. Hope this helps

If you get an error with the error code 35 saying "Unknown SSL protocol error in connection to ...", maybe you are using the wrongs ciphers.

Try to precise a bunch of ciphers as below:

$arrayCiphers = array(
                'DHE-RSA-AES256-SHA',
        'DHE-DSS-AES256-SHA',
        'AES256-SHA:KRB5-DES-CBC3-MD5',

        'DHE-RSA-AES128-SHA',
        'DHE-DSS-AES128-SHA',
        'AES128-SHA:RC2-CBC-MD5',
        'KRB5-RC4-MD5:KRB5-RC4-SHA',
        'RC4-SHA:RC4-MD5:RC4-MD5',
        'KRB5-DES-CBC-MD5',
        'KRB5-DES-CBC-SHA',
        'EDH-RSA-DES-CBC-SHA',
        'EDH-DSS-DES-CBC-SHA:DES-CBC-SHA',
        'DES-CBC-MD5:EXP-KRB5-RC2-CBC-MD5',
        'EXP-KRB5-DES-CBC-MD5',
        'EXP-KRB5-RC2-CBC-SHA',
        'EXP-KRB5-DES-CBC-SHA',

        'EXP-KRB5-RC4-MD5',
        'EXP-KRB5-RC4-SHA',
        'EXP-RC4-MD5:EXP-RC4-MD5'

For those of you wondering how to specify the content-type for a file uploaded via curl, the syntax is as follows:

<?php

$data
= array('file' => '@/home/user/test.png;type=image/png');

?>

Simply adding a semicolon with the type= at the end.
Note that this has been reported not to work in all versions of PHP and I have done the following tests:

5.2.6 (libcurl 7.18.2) : Does not work
5.2.13 (libcurl 7.20.0) : Works just fine

So it might be worth updating your installation of PHP and/or libcurl if you want to be able to use this syntax

If you have turned on conditional gets on a curl handle, and then for a subsequent request, you don't have a good setting for CURLOPT_TIMEVALUE , you can disable If-Modified-Since checking with:

<?php

$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, $foo);
curl_setopt($ch, CURLOPT_TIMEVALUE, filemtime($foo_path));
curl_setopt($ch, CURLOPT_TIMECONDITION, CURLOPT_TIMECOND_IFMODIFIEDSINCE);
curl_exec($ch);
// Reuse same curl handle
curl_setopt($ch, CURLOPT_URL, $bar);
curl_setopt($ch, CURLOPT_TIMEVALUE, null); // don't know mtime
curl_setopt($ch, CURLOPT_TIMECONDITION, 0); // set it to 0, turns it off
curl_exec($ch);

For those using CURLAUTH_NTLM, it may come to no surprise  that NTLM request will fail if you have set CURLOPT_FORBID_REUSE to true.

This is because NTLM authorisation is connect-based, not request-based. If the connection is not kept alive and re-used, cURL can never complete the request.

You may notice this if you get a 401 status code or max out the number of redirects.

Using CURLOPT_NOPROXY to avoid using the proxy for some urls is very convenient.
For example when the page is trying to look for itself.
The parameter can be found at least in version 5.5.7, (probably earlier)
Unfortunately it's not present on debian wheezy (5.4.4) but it will be on jessie (it's already there)

I noticed that if you want to get current cookie file after curl_exec() - you need to close current curl handle (like it said in manual), but if you want cookies to be dumped to file after any curl_exec (without curl_close) you can:

<?php
#call it normally
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiefile");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/');
$result1 = curl_exec($ch);

#and then  make a temp copy
$ch_temp=curl_copy_handle(ch);
curl_close($ch);
$ch=$ch_temp;
?>

Only this way, if you close $ch_temp - cookies wont be dumped.

Another note addressing the issues with servers that have open_basedir and safe mode turned on. Such an issue spawns the following E_WARNING:

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set

After looking through the notes, most of the proposed manual implementations were kind of clunky and in some cases just didn't work at all. Most importantly (in my case), was the behaviour of the 302 Header. Anyway, here's the code I ended up using which has worked well for me in all cases so far, it even addresses the issue that caused FOLLOWLOCATION to be turned off in some cases :)

EDIT: Unfortunately the code itself is deemed "too long" for PHP's note system. I've uploaded it to a few paste sites below so hopefully the links will live for a while at least.

Use it as a replacement for curl_exec. For example:

<?php
$ch
= curl_init("http://php.net");
var_dump(curl_exec_follow($ch, 9001));
curl_close($ch);
?>

Problems can occur if you mix CURLOPT_URL with a 'Host:' header in CURLOPT_HEADERS on redirects because cURL will combine the host you explicitly stated in the 'Host:' header with the host from the Location: header of the redirect response.

In short, don't do this:

<?php
$host
= "www.example.com";
$url = "http://$host/";

$headers = array("Host: $host");

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

Do
this instead:

$host = "www.example.com";
$url = "http://$host/";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
?>

When passing CURLOPT_POSTFIELDS a url-encoded string in order to use Content-Type: application/x-www-form-urlencoded, you can pass a string directly:
<?php
curl_setopt
(CURLOPT_POSTFIELDS, 'field1=value&field2=value2');
?>

rather than passing the string in an array, as in fred at themancan dot com's example.

I've created an example that gets the file on url passed to script and outputs it to the browser.

<?php
//get the file (e.g. image) and output it to the browser
$ch = curl_init(); //open curl handle
curl_setopt($ch, CURLOPT_URL, $_GET['url']); //set an url
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //do not output directly, use variable
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); //do a binary transfer
curl_setopt($ch, CURLOPT_FAILONERROR, 1); //stop if an error occurred
$file=curl_exec($ch); //store the content in variable
if(!curl_errno($ch))
{
   
//send out headers and output
   
header ("Content-type: ".curl_getinfo($ch, CURLINFO_CONTENT_TYPE)."");
   
header ("Content-Length: ".curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD)."");
    echo
$file;
} else echo
'Curl error: ' . curl_error($ch);
curl_close($ch); //close curl handle
?>

p.s. Make sure that there're no new lines before and after code or script may not work.

Just a small detail I too easily overlooked.
<?php
/*  If you set:  */
curl_setopt ($ch, CURLOPT_POST, 1);
/* then you must have the data: */
curl_setopt ($ch, CURLOPT_POSTFIELDS, $PostData);

I found with only the CURLOPT_POST set (from copy, paste editing of course) cookies were not getting sent with CURLOPT_COOKIE.  Just something subtle to watch out for.

In PHP5, for the "CURLOPT_POSTFIELDS" option, we can use:

<?php

$Post = http_build_query($PostData);
curl_setopt($ch, CURLOPT_POSTFIELDS, $Post);
$Output = curl_exec($ch);
curl_close($ch);

The description of the use of the CURLOPT_POSTFIELDS option should be emphasize, that using POST with HTTP/1.1 with cURL implies the use of a "Expect: 100-continue" header. Some web servers will not understand the handling of chunked transfer of post data.

To disable this behavior one must disable the use of the "Expect:" header with

    curl_setopt($ch, CURLOPT_HTTPHEADER,array("Expect:"));

About CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE, and which / how to use.

- CURLOPT_COOKIEJAR is used when cURL is reading cookie data from disk.

- CURLOPT_COOKIEFILE is used when cURL is writing the cookie data to disk.

So you need to specify both (and set the same file location on both) when working with sessions for example.

As of at least PHP 5.3.9, if you are continuing to use a cURL session handle after downloading a file and closing the file handle, you will need to change CURLOPT_FILE back to stdout, and cannot count simply on a side effect of CURLOPT_RETURNTRANSFER to do so, even if you are setting it.  For example:

<?php
$ch
= curl_init();
$fh = fopen('/path/to/stored/file/example_file.dat', 'w');
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_setopt($ch, CURLOPT_URL, 'http://example.com/example_file.dat');
curl_exec($ch);
fflush($fh);
fclose($fh);

//must reset cURL file handle. Not doing so will cause a warning to be
//thrown and for cURL to default to output regardless
//for our example, we'll set return transfer.
curl_setopt($ch, CURLOPT_FILE, fopen('php://stdout', 'w'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL, 'http://example.org/index.html');
$html = curl_exec($ch); //this will now work

A bit more documentation (without minimum version numbers):

- CURLOPT_WRITEFUNCTION
- CURLOPT_HEADERFUNCTION
  Pass a function which will be called to write data or headers respectively. The callback function prototype:

long write_callback (resource ch, string data)

The ch argument is CURL session handle. The data argument is data received. Note that its size is variable. When writing data, as much data as possible will be returned in all invokes. When writing headers, exactly one complete header line is returned for better parsing.
The function must return number of bytes actually taken care of. If that amount differs from the amount passed to this function, an error will occur.

- CURLOPT_READFUNCTION
  Pass a function which will be called to read data. The callback function prototype:

string read_callback (resource ch, resource fd, long length)

The ch argument is CURL session handle. The fd argument is file descriptor passed to CURL by CURLOPT_INFILE option. The length argument is maximum length which can be returned.
The function must return string containing the data which were read. If length of the data is more than maximum length, it will be truncated to maximum length. Returning anything else than a string means an EOF.

[Note: there is more callbacks implemented in current cURL library but they aren't unfortunately implemented in php curl interface yet.]

About the CURLOPT_HTTPHEADER option, it took me some time to figure out how to format the so-called 'Array'. It fact, it is a list of strings. If Curl was already defining a header item, yours will replace it. Here is an example to change the Content Type in a POST:

<?php curl_setopt ($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml")); ?>

Note that if you want to use a proxy and use it as a _cache_, you'll have to do:

else by default Curl puts a "Pragma: no-cache" header in and thus force cache misses for all requests.

You can use also use object methods as callback functions. This is usefull if your curl ressource is part of an object handling transfers.
Instead of curl_setopt($curl, CURLOPT_WRITEFUNCTION, "curl_handler_recv") you can use array($object, "method") as value for callback options.

For example:

<?php
class downloader {
    private
$curl;

    function
__construct() {
       
$this->curl = curl_init();
       
curl_setopt($this->curl, CURLOPT_WRITEFUNCTION, array($this, "curl_handler_recv"));
    }

     function
curl_handler_recv($res, $data) {
     
//...

If you're getting trouble with cookie handling in curl:

- curl manages tranparently cookies in a single curl session
- the option
<?php curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName"); ?>

makes curl to store the cookies in a file at the and of the curl session

- the option
<?php curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookieFileName"); ?>

makes curl to use the given file as source for the cookies to send to the server.

so to handle correctly cookies between different curl session, the you have to do something like this:

<?php
       $ch
= curl_init();
      
curl_setopt ($ch, CURLOPT_URL, $url);
      
curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE_PATH);
      
curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE_PATH);

      
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
      
$result = curl_exec ($ch);
      
curl_close($ch);
       return
$result;
?>

in particular this is NECESSARY if you are using PEAR_SOAP libraries to build a webservice client over https and the remote server need to establish a session cookie. in fact each soap message is sent using a different curl session!!

I hope this can help someone

    else
$vars .= $keyprefix.$key.$keypostfix."=".urlencode($value)."&";
  }
  return
$vars;
}

curl_setopt($ch, CURLOPT_POSTFIELDS, substr(data_encode($_POST), 0, -1) );

When you are using CURLOPT_FILE to download directly into a file you must close the file handler after the curl_close() otherwise the file will be incomplete and you will not be able to use it until the end of the execution of the php process.

<?php

$fh
= fopen('/tmp/foo', 'w');
$ch = curl_init('http://example.com/foo');
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_exec($ch);
curl_close($ch);

# at this point your file is not complete and corrupted

fclose($fh);

# now you can use your file;

read_file('/tmp/foo');

Using cURL, I needed to call a third-party script which was returning binary data as attachment to pass on retrieved data again as attachment.

Problem was that the third-party script occassionally returned HTTP errors and I wanted to avoid passing on zero-length attachment in such case.

Combination of using CURLOPT_FAILONERROR and CURLOPT_HEADERFUNCTION callback helped to process the third-party script HTTP errors neatly:

<?php
function curlHeaderCallback($resURL, $strHeader) {
    if (
preg_match('/^HTTP/i', $strHeader)) {
       
header($strHeader);
       
header('Content-Disposition: attachment; filename="file-name.zip"');
    }
    return
strlen($strHeader);
}

$strURL = 'http://www.example.com/script-whichs-dumps-binary-attachment.php';

$resURL = curl_init();
curl_setopt($resURL, CURLOPT_URL, $strURL);
curl_setopt($resURL, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($resURL, CURLOPT_HEADERFUNCTION, 'curlHeaderCallback');
curl_setopt($resURL, CURLOPT_FAILONERROR, 1);

curl_exec ($resURL);

$intReturnCode = curl_getinfo($resURL, CURLINFO_HTTP_CODE);
curl_close ($resURL);

if (
$intReturnCode != 200) {
    print
'was error: ' . $intReturnCode;
}

If you'd like to include extra headers in your POST request, you can accomplish this by setting the following option:

CURLOPT_HTTPHEADER

This is similar to the CURL -H command line switch.

If you want to connect to a server which requires that you identify yourself with a certificate, use following code. Your certificate and servers certificate are signed by an authority whose certificate is in ca.ctr.

<?php
curl_setopt
($ch, CURLOPT_VERBOSE, '1');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, '2');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, '1');
curl_setopt($ch, CURLOPT_CAINFOgetcwd().'/cert/ca.crt');
curl_setopt($ch, CURLOPT_SSLCERT, getcwd().'/cert/mycert.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'password');
?>

If your original certificate is in .pfx format, you have to convert it to .pem using following commands
# openssl pkcs12 -in mycert.pfx -out mycert.key
# openssl rsa -in mycert.key -out mycert.pem
# openssl x509 -in mycert.key >> mycert.pem

To make a POST in multipart/form-data mode

(to upload a file for example) you can use

<?php curl_setopt($ch,CURLOPT_POSTFIELDS,$post); ?>

where $post is an array :

<?php
$post
['key1'] = 'data1';
//  like a text field in a POST
$post['file1'] = '@filename1'
// upload filename1
?>

If you set CURLOPT_RESUME_FROM to resume the file, and then reuse the same Curl handle to download another file, you must reset the resume status by calling curl_setopt( $ch, CURLOPT_RESUME_FROM, 0 ). It will not reset, and will apply to all subsequent transfers even if the URL is the same.

CURLOPT_HTTPHEADER is NOT like the -H command line switch. The command line switch adds or replaces headers (much like the header() line in PHP, but for HTTP clients instead of servers), but the curl extension will eliminate the headers cURL sends by default.

For instance, your Authorization, Host, Referer, Pragma, and Accept headers which are normally written by default or by other CURLOPT_*'s.

Also, it might seem intuitive that this should accept an array hash of header->values, but this is not the case. It accepts an array of strings of the format "Header: Value", much like the -H command-line switch.

Hope this helps,

terry
