cPanel xmlapi - oprette cronjob

Hej

Jeg skal have lavet et script der opretter et cronjob på en server hvor Cpanel er installeret - jeg kan gennem xmlapi få oprettet subdomæne  - det fungerer fint - men jeg kan ikke få oprettet cronjobbet - kan nogen gennemskue hvad der er galt?

Eller hvis du har en alternativ måde at oprette et cronjob på.
Serveren kører linux

DETTE FUNGERER
------------------------------
<?php
include_once("xmlapi.php");
$cPanelUser = 'cpanel_user';
//Topdomænet hvor subdomænet skal laves på
$cPanelDomain = 'domæne.dk';
//navn på subdomæne
$ipccSub = 'subdir';
// CREATE SUBDOMAIN
$xmlapi->api1_query($cPanelUser, 'SubDomain', 'addsubdomain', array($ipccSub,$cPanelDomain,0,0, $ipccDir));
?>
-----------------------
MEN DETTE FUNGERER IKKE
det her kan jeg ikke få til at fungere - jeg har funder kodestykker på denne side:
