You're trying to reference a Microsoft class that doesn't exist in PHP.
I see in your other recent threads that you've tried to call the Volusion API with cURL. This is a valid approach that I use with PHP. There's no need to adapt the C# example into PHP.
Here is a valid example in PHP using cURL and your URL example:
$api_url = "http://tebkq.mvlce.servertrust.com/net/WebService.aspx?Login=mylogin&EncryptedPassword=mypass&Import=Update";
$api_request = '<?xml version="1.0" encoding="utf-8" ?>';
$api_request .= '<xmldata>';
$api_request .= ' <Products>';
$api_request .= ' <ProductCode>0001</ProductCode>';
$api_request .= ' <StockStatus>5</StockStatus>';
$api_request .= ' </Products>';
$api_request .= '</xmldata>';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $api_request);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type:application/x-www-form-urlencoded; charset=utf-8", "Content-Action:Volusion_API"));
$head = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

I think it's because you need to use namespace of you're XMLHTTP class :
$xml_http = new Your\Namespace\XMLHTTP();
because there is no XMLHTTP class in your file. That's why it is not found
Then if you want to use only XMLHTTP() you need to add a use at the beginning of your file:
use <NAMESPACE>;
If this class is from the global namespace just do it like that :
$xml_http = new \XMLHTTP();
