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 booléen 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.
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_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 silencieusement 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_FTPAPPEND TRUE pour que PHP ajoute les informations au fichier distant, plutôt que de l'écraser.
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.
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.
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_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. Tout comme CURL 7.10, CURL installe un paquet par défaut. CURLOPT_SSL_VERIFYHOST doit aussi être positionnée à 1 ou 0 si CURLOPT_SSL_VERIFYPEER est désactivée (par défaut à 2). 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 entier 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 Soit CURLCLOSEPOLICY_LEAST_RECENTLY_USED , soit CURLCLOSEPOLICY_OLDEST . Il y a trois autres constantes CURLCLOSEPOLICY_ mais CURL ne les supporte pas encore.
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. 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.
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, qui, si la vitesse de 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.
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. 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.

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.
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 "Set-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.
CURLOPT_COOKIEJAR Le nom de fichier pour y sauvegarder tous les cookies internes lorsque la connexion se ferme.
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 POST 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_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. 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.
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_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.
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 Notes
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 une chaîne de caractères qui sera un nom valide de fonction de rappel pour les valeurs suivantes du paramètre option :

Option Définissez le paramètre value à Notes
CURLOPT_HEADERFUNCTION Le nom d'une fonction de rappel qui prend deux paramètres. Le premier est la ressource CURL, le second, une chaîne contenant les données de l'en-tête à écrire. En utilisant cette fonction de rappel, il est de votre responsabilité de l'écriture des données de l'en-tête. Retourne le nombre d'octets écrits.
CURLOPT_PASSWDFUNCTION Le nom d'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_READFUNCTION Le nom d'une fonction de rappel où la fonction de rappel prend deux paramètres. Le premier est la ressource CURL et le second, une chaîne contenant les données à lire. En utilisant cette fonction de rappel, il devient de votre responsabilité de lire les données. Retourne le nombre d'octets lus. Retourne 0 à un signal EOF.
CURLOPT_WRITEFUNCTION Le nom d'une fonction de rappel où la fonction de rappel 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 il échouera.

Valeurs de retour

Cette fonction retourne TRUE en cas de succès, FALSE en cas d'échec.

Historique

Version Description
5.2.10 Ajout de CURLOPT_PROTOCOLS et CURLOPT_REDIR_PROTOCOLS.
5.1.0 Ajout de CURLOPT_AUTOREFERER, CURLOPT_BINARYTRANSFER, CURLOPT_FTPSSLAUTH, CURLOPT_AUTOREFERER, CURLOPT_PROXYAUTH et CURLOPT_TIMECONDITION.
5.0.0 Ajout de CURLOPT_FTP_USE_EPRT, CURLOPT_NOSIGNAL, CURLOPT_UNRESTRICTED_AUTH, CURLOPT_BUFFERSIZE, CURLOPT_HTTPAUTH, CURLOPT_PROXYPORT, CURLOPT_PROXYTYPE, CURLOPT_SSLCERTTYPE et CURLOPT_HTTP200ALIASES.

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.

Following from the comment made by Stan van de Burgt, if you change the post array to a string, PHP creates the post data successfully.

As a quick and dirty example of implementing this fix:

<?php

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

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);

foreach (
$postData as $var) if (strpos($var, '@') === 0) {
   
$postAsString = true;
}

if (
$postAsString === true) {
   
$str = '';

    foreach (
$postData as $key => $val) {
       
$str .= '&' . $key . '=' . $val;
    }

   
$postData = substr_replace($str, '', 0, 1);
}

curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

curl_exec($ch);

?>

Hopefully this error gets fixed at a lower level in the PHP cURL library itself to stop the need for this ugly workaround.

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 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.

There is a function to send POST data in page with five parameters :

$post must be an array
$page is the page where POST datas will be send.
$n must be true to continue if they are php redirection (Location: )
$session must be define true if you want to use cookies
$referer must be a link to get a wrong referer or only to have a referer.

<?php
function curl_data_post($post, $page, $n, $session, $referer)
    {
        if(!
is_array($post))
        {
         return
false;
        }
       
       
$DATA_POST = curl_init();
       
curl_setopt($DATA_POST, CURLOPT_RETURNTRANSFER, true);
       
curl_setopt($DATA_POST, CURLOPT_URL, $page);
       
curl_setopt($DATA_POST, CURLOPT_POST, true);
        if(
$n)
        {
        
curl_setopt($DATA_POST, CURLOPT_FOLLOWLOCATION, true);
        }
        if(
$session)
        {
        
curl_setopt($DATA_POST, CURLOPT_COOKIEFILE, 'cookiefile.txt');
        
curl_setopt($DATA_POST, CURLOPT_COOKIEJAR, 'cookiefile.txt');
        }
       
        if(
$referer)
        {
        
curl_setopt($DATA_POST, CURLOPT_REFERER, $referer);
        }
       
       
curl_setopt($DATA_POST, CURLOPT_POSTFIELDS, $post);
       
$data = curl_exec($DATA_POST);
        if(
$data == false)
        {
         echo
'Warning : ' . curl_error($DATA_POST);
        
curl_close($DATA_POST);
         return
false;
        }
        else
        {
        
curl_close($DATA_POST);
         return
$data;
        }
    }
?>

Whats not mentioned in the documentation is that you have to set CURLOPT_COOKIEJAR to a file for the CURL handle to actually use cookies, if it is not set then cookies will not be parsed.

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');

?>

When using CURLOPT_FILE, pass it the file handle that is open for write only (eg fopen('blahblah', 'w+')). If you also open the file for reading (eg fopen('blahblah', 'rw')), curl will fail with error 23.

Seems like some options not mentioned on this page, but listed on http://curl.haxx.se/libcurl/c/curl_easy_setopt.html is actually supported.

I was happy to see that I could actually use CURLOPT_FTP_CREATE_MISSING_DIRS even from PHP.

As of php 5.3 CURLOPT_PROGRESSFUNCTION its supported here's how:

<?php

function callback($download_size, $downloaded, $upload_size, $uploaded)
{
   
// 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);

?>

Hope this help.

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.

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.

Example how to connect to FTPES (FTP explicit SSL). This script will connect to any FTPES server and out put the list of directories.

<?php
    $username
= 'username';
   
$password = 'password';
   
$url = 'url';
   
$ftp_server = "ftp://" . $username . ":" . $password . "@" . $url;
   
    echo
"Starting CURL.\n";
   
$ch = curl_init();
    echo
"Set CURL URL.\n";
   
   
//curl FTP
   
curl_setopt($ch, CURLOPT_URL, $ftp_server);
   
   
//For Debugging
    //curl_setopt($ch, CURLOPT_VERBOSE, TRUE);   
   
    //SSL Settings
   
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
   
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
   
curl_setopt($ch, CURLOPT_FTP_SSL, CURLFTPSSL_TRY);
   
   
//List FTP files and directories
   
curl_setopt($ch, CURLOPT_FTPLISTONLY, TRUE);
   
   
//Output to curl_exec
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    echo
"Executing CURL.\n";
   
$output = curl_exec($ch);
   
curl_close($ch);
    echo

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.

if unserialize() returns FALSE on a serialized PHP object due to an extraneous string (e.g. "1") appended at the end of the object, you need to set the ff cURL option:

<?php
curl_setopt
($ch, CURLOPT_RETURNTRANSFER, true);
?>

To send a post as a different content-type (ie.. application/json or text/xml) add this setopt call

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADERS,array('Content-Type: application/json'));
?>

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.

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!

This may not be a surprise for many, but I know I bled my eyes out trying to implement this in php. And when I knew it was this simple, I really felt extremely stupid. So I put this just so google will save somebody some time in the future.

PHP NTLM AUTH

Make sure you have the 'curl' extension loaded
now just do...

<?php
curl_setopt
($ch,CURLAUTH_NTLM);
curl_setopt($ch,CURLOPT_USERPWD,"$username:$password");
?>

and just continue to use curl in the ordinary fashion.

To fetch (or submit data to) multiple pages during one session,use this:

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_URL, 'http://example.com/page1.php');
$result1 = curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, 'http://example.com/page2.php');
$result2 = curl_exec($ch);

curl_close($ch);
?>

Some of you may noticed that curl is not transferring cookies between sequent calls to a host. This is because you must activate curl`s "cookie parser". That is achieved using an external file like this:
<?php
curl_setopt
(CURLOPT_FILE, '/tmp/cookies_file');
?>
If you don`t need to read any cookies but you still want the "cookie parser" use the same code but with dummy file with no data like '/dev/null', that way curl is storing cookies internaly per curl_handle:
<?php
curl_setopt
(CURLOPT_FILE, '/dev/null');
?>

[EDIT BY danbrown AT php DOT net: In a note dated 26-SEP-08, (adamplumb AT gmail DOT com) offered the following addendum:

[It] should really be CURLOPT_COOKIEFILE.  I was bitten by this issue myself with code that previously worked for logging into a website and posting a form.  However, at some point the code just stopped working, and I eventually found that I needed to set this option to /dev/null for it to work.

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.

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.

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.

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
    inet 78.24.XXX.XXX netmask 0xffffffff broadcast 78.24.XXX.XXX
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX

    inet 78.24.XXX.XXX netmask 0xffffffff broadcast 78.24.XXX.XXX
    inet 78.24.XXX.XXX netmask 0xffffffff broadcast 78.24.XXX.XXX
    ether XX:XX:XX:XX:XX:XX
    media: Ethernet autoselect (100baseTX <full-duplex>)
    status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
    Opened by PID 564
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
82.146.XXX.XXX
82.146.XXX.XXX
82.146.XXX.XXX
78.24.XXX.XXX
78.24.XXX.XXX

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, '1');
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

Although CURLOPT_CLOSEPOLICY and the applicable choices are valid constants, setting this option with curl_setopt() always returns false. A quick google search suggests the option is deprecated and/or never worked.

Someone posted this under tmpfile (http://us3.php.net/manual/en/function.tmpfile.php#69419), and I thought it was particularly useful:

[The PHP function tmpfile()] is really useful for libcurl's CURLOPT_PUT feature if what you're trying to PUT is a string.   For example:

<?php
/* Create a cURL handle. */
$ch = curl_init();

/* Prepare the data for HTTP PUT. */
$putString = "Hello, world!";
$putData = tmpfile();
fwrite($putData, $putString);
fseek($putData, 0);

/* Set cURL options. */
curl_setopt($ch, CURLOPT_URL, "http://www.example.com");
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_INFILE, $putData);
curl_setopt($ch, CURLOPT_INFILESIZE, strlen($putString));
/* ... (other curl options) ... */

/* Execute the PUT and clean up */
$result = curl_exec($ch);
fclose($putData);
curl_close($ch);
?>

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

<?php
$ch
= curl_init($URI);
$Post = http_build_query($PostData);
curl_setopt($ch, CURLOPT_POSTFIELDS, $Post);
$Output = curl_exec($ch);
curl_close($ch);
?>

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/

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);
}
?>

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 ;)

If you try to upload file to a server, you need do CURLOPT_POST first and then fill CURLOPT_POSTFIELDS.

<?php
curl_setopt
($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
// ^^ This will post multipart/form-data

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

// Read the XML to send to the Web Service
        
$request_file = "./SampleRequest.xml";

$xml_data = fread($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);
           
curl_close($ch);
        }

?>

hey hey hey!
the problem: curl_setopt($ch,FOLLOW_LOCATION,1);
the error: trouble with open_basedir and safe_mode
the solution: a function already developed by someone
the solution n 2: the same function, modifed, works great for me..

<?php
function curl_redir_exec($ch,$debug="")
{
    static
$curl_loops = 0;
    static
$curl_max_loops = 20;

    if (
$curl_loops++ >= $curl_max_loops)
    {
       
$curl_loops = 0;
        return
FALSE;
    }
   
curl_setopt($ch, CURLOPT_HEADER, true);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   
$data = curl_exec($ch);
   
$debbbb = $data;
    list(
$header, $data) = explode("\n\n", $data, 2);
   
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    if (
$http_code == 301 || $http_code == 302) {
       
$matches = array();
       
preg_match('/Location:(.*?)\n/', $header, $matches);
       
$url = @parse_url(trim(array_pop($matches)));
       
//print_r($url);
       
if (!$url)
        {
           
//couldn't process the url to redirect to
           
$curl_loops = 0;
            return
$data;
        }
       
$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
   
/*    if (!$url['scheme'])
            $url['scheme'] = $last_url['scheme'];
        if (!$url['host'])
            $url['host'] = $last_url['host'];
        if (!$url['path'])
            $url['path'] = $last_url['path'];*/
       
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
       
curl_setopt($ch, CURLOPT_URL, $new_url);
   
//    debug('Redirecting to', $new_url);

       
return curl_redir_exec($ch);
    } else {
       
$curl_loops=0;
        return
$debbbb;
    }
}
?>

just use this function without de FOLLOW_LOCATION and should work. the problem was that when you get to the line where you return the data if http_code was different than 301 oe 302, $data has obsolete information or none. so $debbbb does the job.

hope this helps someone out there

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.

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 connect to 'https://...' and after that want to work with POST data - that's the way:

<?php
$curl
= curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($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);

curl_setopt($curl, CURLOPT_URL, "url2"); # this is where you are requesting POST-method form results (working with secure connection using cookies after auth)
curl_setopt($curl, CURLOPT_POSTFIELDS, "var1=value&var2=value&var3=value&"); # form params that'll be used to get form results
$xxx = curl_exec($curl);

curl_close ($curl);
echo
$xxx;

Two things that I noted, one of which has been mentioned earlier, if you are connecting to an SSL site (https) and don't have the appropriate certificate, don't forget to set CURLOPT_SSL_VERIFYPEER as "false"... it's set to "true" by default. Scratched my head over 2 hours to figure this one out as I had a machine with an older version installed and everything worked fine without using this option on that one - but failed on other machines with newer versions.

Second very important thing, I've never had my scripts work (tried on various machines, multiple platforms) with a Relative path to a COOKIEJAR or COOKIEFILE. In my experience I HAVE to specify the absolute path and not the relative path.

Small script I wrote to connect to a page, gather all cookies into a jar, connect to another page to login, taking the cookiejar with you for authentication:

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "/Library/WebServer/Documents/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"https://www.example.com/myaccount/start.asp");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
ob_start();      // Prevent output
curl_exec ($ch);
ob_end_clean();  // End preventing output
curl_close ($ch);
unset(
$ch);

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "field1=".$f1."&field2=".$f2."&SomeFlag=True");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_COOKIEFILE, "/Library/WebServer/Documents/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"https://www.example.com/myaccount/Login.asp");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec ($ch);
curl_close ($ch);
?>

If you are getting the following error:

SSL: certificate subject name 'example.com' does not match target host name 'example.net'

Then you can set the following option to get around it:

<?php curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); ?>

Please note that the CURLOPT_INTERFACE setting only accepts IP addresses and hostnames of the local machine. It is not meant to send a URL to a specific IP address.

In case you wonder how come, that cookies don't work under Windows, I've googled for some answers, and here is the result: Under WIN you need to input absolute path of the cookie file.

This piece of code solves it:

<?php

if ($cookies != '')
    {
    if (
substr(PHP_OS, 0, 3) == 'WIN')
        {
$cookies = str_replace('\\','/', getcwd().'/'.$cookies);}
   
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies);
   
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookies);
    }

?>

Options not included in the above, but that work (Taken from the libcurl.a C documentation)

CURLOPT_FTP_SSL

Pass a long using one of the values from below, to make libcurl use your desired level of SSL for the ftp transfer. (Added in 7.11.0)

CURLFTPSSL_NONE

Don't attempt to use SSL.

CURLFTPSSL_TRY

Try using SSL, proceed as normal otherwise.

CURLFTPSSL_CONTROL

Require SSL for the control connection or fail with CURLE_FTP_SSL_FAILED.

CURLFTPSSL_ALL

Require SSL for all communication or fail with CURLE_FTP_SSL_FAILED.

Seems that CURLOPT_RETURNTRANSFER Option set to TRUE, returns a "1" when the transaction returns a blank page.

I think is for eliminate the FALSE to can be with a blank page as return

How to get rid of response after POST: just add callback function for returned data (CURLOPT_WRITEFUNCTION) and make this function empty.

<?php
function curlHeaderCallback($ch, $strHeader) {
}
curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'curlHeaderCallback');
?>

I was having problems with Authorize.net and the SSL cert matching even after adding:

<?php
curl_setopt
($ch, CURLOPT_SSL_VERIFYPEER, 0);
?>

What I found after a lot of stumbling was I needed to set VERIFYHOST to FALSE.  So if you are still have a problem with Authorize.NET SSL and cURL add this:

<?php
curl_setopt
($ch, CURLOPT_SSL_VERIFYHOST, 0);
?>

I was working on using php to interface with an authorize.net gateway, and I ran into a problem with certificates using curl to talk the https:// url.

curl_error() told me "SSL certificate problem, verify that the CA cert is OK."

I googled it and found the same "solution" over and over again: bypass verification by adding this line after curl_init():

<?php
curl_setopt
($connection, CURLOPT_SSL_VERIFYPEER, false);
?>

This worked great, but I was required to verify, so here's what I did. Add the following lines:

<?php
curl_setopt
($connection, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($connection, CURLOPT_CAINFO, "path:/ca-bundle.crt");
?>

with "path:/ca-bundle.crt" being the path to that certificate file. You can get this file by downloading the curl package (http://curl.haxx.se/download.html) and looking for it in the lib folder.

Feel free to email me.

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
   
function curl_redir_exec($ch)
    {
        static
$curl_loops = 0;
        static
$curl_max_loops = 20;
        if (
$curl_loops++ >= $curl_max_loops)
        {
           
$curl_loops = 0;
            return
FALSE;
        }
       
curl_setopt($ch, CURLOPT_HEADER, true);
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       
$data = curl_exec($ch);
        list(
$header, $data) = explode("\n\n", $data, 2);
       
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        if (
$http_code == 301 || $http_code == 302)
        {
           
$matches = array();
           
preg_match('/Location:(.*?)\n/', $header, $matches);
           
$url = @parse_url(trim(array_pop($matches)));
            if (!
$url)
            {
               
//couldn't process the url to redirect to
               
$curl_loops = 0;
                return
$data;
            }
           
$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
            if (!
$url['scheme'])
               
$url['scheme'] = $last_url['scheme'];
            if (!
$url['host'])
               
$url['host'] = $last_url['host'];
            if (!
$url['path'])
               
$url['path'] = $last_url['path'];
           
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
           
curl_setopt($ch, CURLOPT_URL, $new_url);
           
debug('Redirecting to', $new_url);
            return
curl_redir_exec($ch);
        } else {
           
$curl_loops=0;
            return
$data;
        }
    }

As Yevgen mentioned earlier sometimes we can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE. Below is a header callback function I wrote back in January that lets you maintain cookies between cURL requests. Cookies are added to $ch during all requests even during redirection, so you can use it together with CURLOPT_FOLLOWLOCATION.
Here is the code:

<?php
function read_header($ch, $string)
{
    global
$location; #keep track of location/redirects
   
global $cookiearr; #store cookies here
   
global $ch;
      
# ^overrides the function param $ch
       # this is okay because we need to
       # update the global $ch with
       # new cookies
   
   
$length = strlen($string);
    if(!
strncmp($string, "Location:", 9))
    {
#keep track of last redirect
     
$location = trim(substr($string, 9, -1));
    }
    if(!
strncmp($string, "Set-Cookie:", 11))
    {
#get the cookie
     
$cookiestr = trim(substr($string, 11, -1));
     
$cookie = explode(';', $cookiestr);
     
$cookie = explode('=', $cookie[0]);
     
$cookiename = trim(array_shift($cookie));
     
$cookiearr[$cookiename] = trim(implode('=', $cookie));
    }
   
$cookie = "";
    if(
trim($string) == "")
    { 
#execute only at end of header
     
foreach ($cookiearr as $key=>$value)
      {
       
$cookie .= "$key=$value; ";
      }
     
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
    }

    return
$length;
}
?>

Using the header function with curl (add this before curl_exec):

<?php
#don't forget globals, especially if you are using this in function
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header');
?>

This code assumes that you will reuse $ch without initializing it every time (call curl_init only once, in the beginning). If you need to initialize $ch again at any point in your code you can access the currently stored cookies in $cookiearr and include them in the new $ch.

I wrote this function before I had enough experience with regular expressions so you won't find any preg_match calls here. I have used this code for quite a while and without any problems accessing gmail, yahoo, hotmail, aol etc. where I had to go through login and a few pages before getting to what I was looking for.

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

<?php curl_setopt($ch, CURLOPT_HTTPHEADER, array("Pragma: ")); ?>

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

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.

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

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://us3.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";
?>

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

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.

There is really a problem of transmitting $_POST data with curl in php 4+ at least.
I improved the encoding function by Alejandro Moreno to work properly with mulltidimensional arrays.

assert( is_array($data) );
 
$vars=null;
  foreach(
$data as $key=>$value) {
    if(
is_array($value)) $vars .= data_encode($value, $keyprefix.$key.$keypostfix.urlencode("["), urlencode("]"));
    else
$vars .= $keyprefix.$key.$keypostfix."=".urlencode($value)."&";
  }
  return
$vars;
}

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

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.

After setting CURLOPT_FILE, you may want want to revert back to the normal behaviour of displaying the results. This can be achieved using:

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);

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;
}

Another way to automate a login process and store multiple cookies for additional transfers.

(The easiest way is probably just to use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE and save them to a file. But if you need to change those cookie values or add/delete them then you can use the code below to set them.)

Continuing with Paul Ebermann's parsing function.

<?php
 
function parse_response($this_response)
    {
   
// Split response into header and body sections
   
list($response_headers, $response_body) = explode("\r\n\r\n", $this_response, 2);
   
$response_header_lines = explode("\r\n", $response_headers);

   
// First line of headers is the HTTP response code
   
$http_response_line = array_shift($response_header_lines);
    if(
preg_match('@^HTTP/[0-9]\.[0-9] ([0-9]{3})@',$http_response_line, $matches)) { $response_code = $matches[1]; }

   
// put the rest of the headers in an array
   
$response_header_array = array();
    foreach(
$response_header_lines as $header_line)
        {
        list(
$header,$value) = explode(': ', $header_line, 2);
       
$response_header_array[$header] .= $value."\n";
        }

    return array(
"code" => $response_code, "header" => $response_header_array, "body" => $response_body);
    }

// Do transfer, and make sure to include header in response
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "[login process]");
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// Parse the response message
$response = parse_response($response);

// Create the basic header
$this_header = array(
   
"MIME-Version: 1.0",
   
"Content-type: text/html; charset=iso-8859-1",
   
"Content-transfer-encoding: text"
);

// Add each cookie that has been returned in the response

The parse_response code below does not return multiple cookies as the value of 'Set-Cookie' if multiple cookies are set by the server.  It appears to only return the last cookie set.

Hi!

I have found some information I am sure it could help lot of programmers when they want to connect with curl to any https website and they haven't a good or right CA Cert :)

I give you just one example It has resolved me 2 hours of my time looking for a solution.

It is simple, just if you get any error in the curl_exec (use curl_error(...) to see the error to trace it) add the next line and everything is solved:

(note: replace $ch with the right curl variable)

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

<?php

$ch
= curl_init();
$res= curl_setopt ($ch, CURLOPT_URL,"https://yoururl/cgi");

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "Idc=si&");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$xyz = curl_exec ($ch);

curl_close ($ch);
echo
$xyz;
if (
$xyz == NULL) {
           echo
"Error:<br>";
           echo
curl_errno($ch) . " - " . curl_error($ch) . "<br>";
}
?>

I hope this helps.

If you specify a CAINFO, note that the file must be in PEM format! (If not, it won't work).
Using Openssl you can use:
openssl x509 -in <cert> -inform d -outform PEM -out cert.pem
To create a pem formatted certificate from a binary certificate (the one you get if you download the ca somewhere).

I found it very annoying that cURL did not offer any easy way to extract the response headers. If you do

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

then you only get the headers output inline with the rest of your response. Here's a nice little function to parse the cURL response when you use CURLOPT_HEADER.  I took it from an example on another site and turned it into a function. It assumes you're using CURLOPT_RETURNTRANSFER to return the response to some variable that is then passed to the function. You just pass it a curl_exec result and it returns the result parsed into an array with headers broken up into their correct parts.

<?php
function parse_response($response){
   
/*
    ***original code extracted from examples at
    ***http://www.webreference.com/programming/php/cookbook/chap11/1/3.html

    ***returns an array in the following format which varies depending on headers returned

        [0] => the HTTP error or response code such as 404
        [1] => Array
        (
            [Server] => Microsoft-IIS/5.0
            [Date] => Wed, 28 Apr 2004 23:29:20 GMT
            [X-Powered-By] => ASP.NET
            [Connection] => close
            [Set-Cookie] => COOKIESTUFF
            [Expires] => Thu, 01 Dec 1994 16:00:00 GMT
            [Content-Type] => text/html
            [Content-Length] => 4040
        )
        [2] => Response body (string)
*/

   
list($response_headers,$response_body) = explode("\r\n\r\n",$response,2);
   
$response_header_lines = explode("\r\n",$response_headers);

   
// first line of headers is the HTTP response code
   
$http_response_line = array_shift($response_header_lines);
    if (
preg_match('@^HTTP/[0-9]\.[0-9] ([0-9]{3})@',$http_response_line,
                  
$matches)) {
       
$response_code = $matches[1];
    }

   
// put the rest of the headers in an array
   
$response_header_array = array();
    foreach (
$response_header_lines as $header_line) {
        list(
$header,$value) = explode(': ',$header_line,2);
       
$response_header_array[$header] = $value;
    }

    return array(
$response_code,$response_header_array,$response_body);
}

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.]

The page http://curl.haxx.se/libcurl/c/curl_easy_setopt.html at the cURL site has a list of all the CURLOPTS, including many not mentioned here. Also see http://curl.haxx.se/libcurl/php/examples/ for cURL examples in PHP.

I managed to use curl to retrieve information from severs on ports other than 80 or 443 (for https) on some installations but not on all.
If you get an "CURLE_COULDNT_CONNECT /* 7 */" error, try adding the port : (for example)

<?php curl_setopt($ch, CURLOPT_PORT, $_SERVER['SERVER_PORT']); ?>

Just a reminder: When setting your CURLOPT_POSTFIELDS remember to replace the spaces in your values with %20

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

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")); ?>

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 set return transfer to 1 and are sending a post form and find that this crashes php try setting follow location to 1 also. I'm not exactly sure why this crashed, but after i used follow it stopped.

<?php
  curl_setopt
($sess, CURLOPT_FOLLOWLOCATION, '1');
 
curl_setopt ($sess, CURLOPT_RETURNTRANSFER, '1');
?>

To make a POST in multipart/form-data mode
this worked for me, the " \n" at the end of the variables was very important on my OS X server.

<?php

$file
= "file_to_upload.txt";
$submit_url = "http://www.example.com/upload_page.php";

$formvars = array("cc"=>"us \n");
$formvars[variable_1] = "bla bla \n";
$formvars[variable_2] = "bla bla \n";
$formvars[variable_3] = "bla bla \n";
$formvars[variable_4] = "bla bla \n";
$formvars[upfile] = "@$file"; // "@" causes cURL to send as file and not string (I believe)

    // init curl handle
   
$ch = curl_init($submit_url);
   
curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt");  //initiates cookie file if needed
   
curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt");  // Uses cookies from previous session if exist
   
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.net");  //if server needs to think this post came from elsewhere
   
curl_setopt($ch, CURLOPT_VERBOSE, 1);
   
curl_setopt($ch, CURLOPT_HEADER, 1);
   
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1); // follow redirects recursively
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
curl_setopt($ch, CURLOPT_POSTFIELDS, $formvars);

   
// perform post
   
echo $pnp_result_page = curl_exec($ch);
   
curl_close ($ch);

?>

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,

It's possible to take advantage of multiple URLs on the same host in one curl_exec transaction ... just use multiple instances of CURLOPT_URL.

Example:

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/a.html");
curl_setopt($ch, CURLOPT_URL, "http://example.com/b.html");
curl_setopt($ch, CURLOPT_URL, "http://example.com/c.html");
curl_exec($ch);
curl_close($ch);
?>

... the URLs appear to be hit in the same order they are entered. This takes advantage of cURL's Persistant Connection capability if all the URLs are on the same host!

To collect cookies recieved with a request, set CURLOPT_COOKIEJAR "cookieFileName".  Then use CURLOPT_COOKIEFILE "cookieFileName" to recall them in subsequent transactions.

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
?>

For more informations see the

curl_formparse man page.

CURLOPT_RETURNTRANSFER has the interesting behaviour of tacking a null char onto the end of the string.  This null char is actually on the end of the php string, and can cause some odd results if you're not expecting it to be there.

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'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.

Thanks to Daniel Stenberg for pointing out this usefull feature!

Note: this option was first supported in PHP version 4.03 .

Just because the docs are rather sparse on this, to set multiple values in a cookie, you separate them with a semicolon, as usual. An example, yo set j to j and k to k:

<?php curl_setopt($ch,CURLOPT_COOKIE,"j=j;k=k"); ?>

I used to download www pages to my script and one of the pages was different in MS explorer and different, when I downloaded it. Namely, information, I was really interested in was missing. That was because the server on the other bank of the river was looking at who is downloading the page. Everything got fixed when I pretended I was MSIE. It is done with curl. Here is a function, that you may use in similar situation

<?php
function download_pretending($url,$user_agent) {
  
$ch = curl_init();
  
curl_setopt ($ch, CURLOPT_URL, $url);
  
curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);
  
curl_setopt ($ch, CURLOPT_HEADER, 0);
  
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
  
$result = curl_exec ($ch);
  
curl_close ($ch);
   return
$result;
}
?>
