<?php
// ftp connection
$ftp = ftp_connect('ftp.example.com');
ftp_login($ftp, 'user', 'password');
// get the system type
if ($type = ftp_systype($ftp)) {
echo "Example.com is powered by $type\n";
} else {
echo "Couldn't get the systype";
}
?>
The above example will output
something similar to:
Example.com is powered by UNIX
