Examples

Example #1 ftp_systype() example

<?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
