ftp_fget
(PHP 4, PHP 5)
ftp_fget — Scarica 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, $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
resumepose' 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().

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;
}

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.
