[twitter-dev] Delete a Direct Message

[Pj]

How to Delete a Direct message in PHP
this is my script:

function deleteDirectMessage($id)
        {
                if (!is_numeric($id)) {
                        return false;
                }
                $request = 
'http://twitter.com/direct_messages/destroy/'.$id.'.xml';


                return $this->process($request);
        }

I found out that the request must be passed as a HTTP request (POST /
DELETE) How to do this?

thanks
