Getting a list of COM Domain objects in Windows XP

[AViS]

Hi,

I am new to PHP. I found the below code at http://in.php.net/com

Example 3. foreach in PHP 5
=============================
<?php
$domainObject = new COM("WinNT://Domain");
foreach ($domainObject as $obj) {
echo $obj->Name . "<br />";
}
?>

But I get no response from the browser (both IE and Firefox 1.0.7). I
wrote a few php pages that DO NOT access COM objects, and all the pages
work fine.

I am running php 5/ Apache 2.2.3/ Win XP SP2

Thanks in advance
Siv
