ftp_nlist() or ftp_rawlist() takes ages then returns nothing...

If you are having this issue, you may need to enable PASV mode FTP transfers using the ftp_pasv() function.

Example...

<?php
$ftp_host = "yourFTPHost";
$ftp_user = "yourUsername";
$ftp_password = "yourPassword";

//Connect
echo "<br />Connecting to $ftp_host via FTP...";
$conn = ftp_connect($ftp_host);
$login = ftp_login($conn, $ftp_user, $ftp_password);

//
//Enable PASV ( Note: must be done after ftp_login() )
//
$mode = ftp_pasv($conn, TRUE);

//Login OK ?
if ((!$conn) || (!$login) || (!$mode)) {
   die("FTP connection has failed !");
}
echo "<br />Login Ok.<br />";

//
//Now run ftp_nlist()
//
$file_list = ftp_nlist($conn, "");
foreach ($file_list as $file)
{
  echo "<br>$file";
}

//close
ftp_close($conn);

?>
