예제
Example #1 ftp_fget() example
<?php
// path to remote file
$remote_file = 'somefile.txt';
$local_file = 'localfile.txt';
// open some file to write to
$handle = fopen($local_file, 'w');
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// try to download $remote_file and save it to $handle
if (ftp_fget($conn_id, $handle, $remote_file, FTP_ASCII, 0)) {
echo "successfully written to $local_file\n";
} else {
echo "There was a problem while downloading $remote_file to $local_file\n";
}
// close the connection and the file handler
ftp_close($conn_id);
fclose($handle);

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.
