ftp_get — Télécharge un fichier depuis un serveur FTP
Description
bool ftp_get
( resource $ftp_stream
, string $local_file
, string $remote_file
, int $mode
[, int $resumepos
] )
ftp_get() télécharge le fichier remote_file depuis le serveur FTP, et le sauve dans le fichier local local_file .
Liste de paramètres
- ftp_stream
-
L'identifiant du lien de connexion FTP.
- local_file
-
Le chemin vers le fichier local (sera écrasé si le fichier existe déjà).
- remote_file
-
Le chemin vers le fichier distant.
- mode
-
Le mode de transfert. Doit être soit FTP_ASCII, soit FTP_BINARY.
- resumepos
-
La position dans le fichier distant à partir duquel on commence le téléchargement.
Valeurs de retour
Cette fonction retourne TRUE en cas de succès, FALSE en cas d'échec.
Exemples
Exemple #1 Exemple avec ftp_get()
<?php
// Définition de quelques variables

// Identification avec un nom d'utilisateur et un mot de passe
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// Tentative de téléchargement du fichier $server_file et sauvegarde dans le fichier $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
echo "Le fichier $local_file a été écris avec succès\n";
} else {
echo "Il y a un problème\n";

Crud. The _nb_ only refers to reading from the ftp server, and the buffer in the socket pair is only about 364 bytes. So it doesn't work for files larger than that size.

Why there isn't an "ftp_get_contents" function, I don't know. It takes a little work to emulate one, but it's doable.
<?php
function ftp_get_contents($ftp_stream, $remote_file, $mode, $resume_pos=null){
$pipes=stream_socket_pair(STREAM_PF_UNIX, STREAM_SOCK_STREAM, STREAM_IPPROTO_IP);
if($pipes===false) return false;
if(!stream_set_blocking($pipes[1], 0)){
fclose($pipes[0]); fclose($pipes[1]);
return false;
}
$fail=false;
$data='';
if(is_null($resume_pos)){
$ret=ftp_nb_fget($ftp_stream, $pipes[0], $remote_file, $mode);
} else {
$ret=ftp_nb_fget($ftp_stream, $pipes[0], $remote_file, $mode, $resume_pos);
}
while($ret==FTP_MOREDATA){
while(!$fail && !feof($pipes[1])){
$r=fread($pipes[1], 8192);
if($r==='') break;
if($r===false){ $fail=true; break; }
$data.=$r;
}
$ret=ftp_nb_continue($ftp_stream);
}
while(!$fail && !feof($pipes[1])){
$r=fread($pipes[1], 8192);
if($r==='') break;
if($r===false){ $fail=true; break; }
$data.=$r;
}
fclose($pipes[0]); fclose($pipes[1]);
if($fail || $ret!=FTP_FINISHED) return false;
return $data;
}
?>
Something similar would work to write a ftp_put_contents function, too.

Hello everybody,
If someone will try to download files to the same local file (some temporary file), like shown here:
<?php
foreach ($files as $key=>$path) {
...
$result = ftp_get($ftpConnId, 'temp.tmp', $path, FTP_BINARY);
...
}
?>
please take in consideration the fact that you will have big problems with downloading (getting) hole files. In other words ‘temp.tmp’ file always will have the same size equal to first downloaded file despite the real size of downloading file. I have not idea what is the reason!
If someone will think that problem is just in getting proper file size (which you will get using filssize() function) he will be mistaken. The download file’s size is not equal to source file’s size materially, that means fflush() function will not solve the problem (I have tried this as well).
Finally the solution was founded: before downloading a file you will need to delete local file if such exist (‘temp.tmp’). So working code will look like:
<?php
foreach ($files as $key=>$path) {
...
if (file_exists('temp.tmp')) {
unlink('temp.tmp');
}
$result = ftp_get($ftpConnId, 'temp.tmp', $path, FTP_BINARY);
...
}
?>
Good luck in scripting :-)

The zero size file is not a side effect. When the ftp_get starts the first thing it does is to create the inode/file which it will stream the data too and that is a zero size file with the nname you specified for the local file. When the download fails it leaves the file in place.

If you previously downloaded a file before (like a huge web log), and just want to get the remaining portion, do this:
$local_file_size = filesize($local_file_path);
$get_result = ftp_get($conn_id, $local_file_path, $remote_file_path, FTP_BINARY, $local_file_size);
This same code works regardless of wether the local file exists already or not. You should first test to make sure the local file is not bigger than the remote file.

Keep in mind that ftp_get will overwrite the file on your local machine if it has the same name.
