ftp_ssl_connect
ftp_systype does NOT appear to be a reliable way to detect whether it is connected, as at least for a local network connection I have here to a Windows ftp server, it can succeed without a working connection (is it cached?). Don't know if this is specific to our ftp server - perhaps it doesn't behave well when it times out links.

Exemples
Exemple #1 Exemple avec ftp_systype()
<?php
// Connexion ftp
$ftp = ftp_connect('ftp.example.com');
ftp_login($ftp, 'user', 'password');
// Récupération du type de serveur
if ($type = ftp_systype($ftp)) {
echo "Example.com est exécuté par $type\n";

ftp_systype can be a good way of checking the state of a connection, since PHP doesn't have a better system to check the state of an ftp connection (is_connected would be nice).
if (!($type = ftp_systype($conn_id))) {
echo "FTP connection has failed! Trying again.\n";
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);
}
