<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

</soap:Envelope>
i want to know how to make the request and how to handle response if this had to be done in php. i read this but i can't figure out how would __setSoapHeaders() and __call() be implemented in my case. thanks in advance.

There's a SOAP library for PHP, but for a simple exchange you might consider building XML request body as a string and the dispatch it using the curl library function. It's a much more low-level network api, which I at least find easier to use. Note that PHP needs to be compiled --with-curl[=DIR].
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $uri);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
if ((bool)$proxy) {
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Pragma:','Cache-Control:'));
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
// Apply the XML to our curl call
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);
$out = curl_exec($ch);
curl_close($ch);
?>
