My FTP-Server always responded "bool(false)" instead of presenting me a directory-listing. I had to add
ftp_pasv($conn_id, true); right after the $login_result = ftp_login(...); line.
After that it just worked fine.

I used following code successfully to connect to "lftp" server and see the complete dir listing.

also ftp_pasv($conn_id, true); trick works fine for lftp server :)


<?php

// set up basic connection

$ftp_server = "example.com";

$conn_id = ftp_ssl_connect($ftp_server);


// login with username and password

$ftp_user_name = "myuser";

$ftp_user_pass = "mypass";

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

ftp_pasv($conn_id, true);

// check connection

if ((!$conn_id) || (!$login_result)) {

        echo "FTP connection has failed!";

        echo "Attempted to connect to $ftp_server for user $ftp_user_name";

        exit;

    } else {

        echo "Connected to $ftp_server, for user $ftp_user_name";

    }


$buff = ftp_rawlist($conn_id, '.');

var_dump($buff);

ftp_close($conn_id);  

?>



Thanks ,
