    ftp_fget

    (PHP 4, PHP 5, PHP 7, PHP 8)

    ftp_fget — Scarica un file dal server FTP e lo salva su un file aperto

    Descrizione

    ftp_fget(
        resource $ftp_stream,
        resource $handle,
        string $remote_file,
        int $mode,
        int $resumepos = ?
    ): bool

    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, $file, FTP_ASCII, 1)) {
    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.

    Vedere anche ftp_get(), ftp_nb_get() e ftp_nb_fget().

    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']);
    }
    ?>

    if you are using windows ftp-server with cp1251 encoding there are some troubles with russian "я" in filename\path.

    php use telnet to connect ftp-server and there are special symbol with code 255 in telnet protocol. You can try use ftp_raw($connection, 'OPTS UTF8 ON'); and work in utf-8 (if server provides it).

    P.S. sorry for my bad english

    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.

    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;
    }

    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.
