PHP 5.5.16 is released

ftp_fget

(PHP 4, PHP 5)

ftp_fgetScarica un file dal server FTP e lo salva su un file aperto

Descrizione

bool ftp_fget ( resource $ftp_stream , resource $handle , string $remote_file , int $mode [, int $resumepos ] )

ftp_fget() recupera remote_file dal server FTP, e lo scrive sul file specificato dal puntatore, handle. Il modo di trasferimento mode specificato deve essere FTP_ASCII oppure FTP_BINARY.

Example #1 Esempio di funzione ftp_fget()

<?php

// apre in lettura un qualche file
$file 'somefile.txt';
$fp fopen($file'w');

// stabilisce la connessione
$conn_id ftp_connect($ftp_server);

// si collega con nome utente e password
$login_result ftp_login($conn_id$ftp_user_name$ftp_user_pass);

// prova a scaricare $file
if (ftp_fget($conn_id$fp$fileFTP_ASCII1)) {
 echo 
"scrittura su $file completata con successo\n";
} else {
 echo 
"Problemi con $file\n";
}

// chiude la connessione e l'handle del file
ftp_close($conn_id);
fclose($fp);
?>

Nota:

Il parametro resumepos e' stato aggiunto in PHP 4.3.0.

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

If you suply only a filename to the second parameter of function the ftp_get will open a pointer to the local file creating it and write to it.It's ok if your server dont execute for to mutch time and you dont get too many files but if you do it too many times the pointers created by ftp_get will not be closed and will end your opened files capacity at your server making it to do not open any more files until you restart it.

You might need to use ftp_pasv() if you're behind a firewall and receiving odd timeouts, file creation but now local data saving, etc.

Another ftp_get_contents approach, using a temperary stream handler. Returns file contents as string.

<?php
function ftp_get_contents ($conn_id, $filename,
//Create temp handler:
   
$tempHandle = fopen('php://temp', 'r+');

//Get file from FTP assuming that it exists:
   
ftp_fget($conn_id, $tempHandle, $filename, FTP_ASCII, 0));

   
//Getting detailed stats to check filesize:
   
$fstats = fstat($tempHandle);

    return
fread($tempHandle, $fstats['size']);
}
?>

I was in need to synchronize two folders on two separate servers, one is a Windows server, and the other is a Linux server. I created this short and sweet function to help me do this. PLEASE NOTICE: This will not copy folders, and probably will fail if remote folder contains anything else than files.

function sync_folders($host, $port, $username, $password, $remote_dir, $local_dir, $passive_mode = true) {
    $conn_id = ftp_connect($host, $port);
    if (!$conn_id) return false; # fail to connect
    if (!ftp_login($conn_id, $username, $password)) { ftp_close($conn_id); return false; }  # fail to login
    ftp_pasv($conn_id, $passive_mode);
    if (!ftp_chdir($conn_id, $remote_dir)) { ftp_close($conn_id); return false; } # fail to change dir
    if (substr($local_dir, -1) != '/') $local_dir .= '/';

    $list = ftp_nlist($conn_id, '.');
    sort($list);
    foreach ($list as $file) {
        if (!file_exists($local_dir . $file)) {
            $is_copied = ftp_get($conn_id, $local_dir . $file, $file, FTP_BINARY);
        }
    }
    ftp_close($conn_id);
    return true;
}

<?php
/**
* Function returns contents via FTP connection and returns it as string (right version...)
*/
function ftp_get_contents ($conn_id, $filename) {
   
//Create temp handler:
   
$tempHandle = fopen('php://temp', 'r+');
   
   
//Get file from FTP:
   
if (@ftp_fget($conn_id, $tempHandle, $filename, FTP_ASCII, 0)) {
       
rewind($tempHandle);
        return
stream_get_contents($tempHandle);
    } else {
