XML API 2 help

[Dragonxito]

What is wrong here? Thanks in advance

<?php
require_once('xmlapi.php'); 

$ip = 'www.mydomain.com';
$account = 'cp_user';
$pass = 'cp_password';

$xmlapi = new xmlapi($ip);
$xmlapi->password_auth($account,$pass);
$xmlapi->set_output("json");

$xmlapi->set_debug(1);
print $xmlapi->api2_query($account, 'SubDomain','addsubdomain', array('dir'=>'/public_html/subdomain/','disallowdot'=>1,'domain'=>'subdomain','rootdomain'=>'www.mydomain.com'));
?>

If you are using a user's credentials and not root, you need to do an $xmlapi->set_port(2083); before you attempt the query.
