将XML订购到soap客户端

I have to make a script that sends a order (XML) to a SOAP client server (this way the supplier can handle the order)

I tried everything but it doesn't work.

Does anybody know what I'm doing wrong?

This is what I have so far:

<?php
$xmlstr = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
