Hi, you can use mi snippet. I used it to test WCF service. :)
<?php
//Data, connection, auth
$dataFromTheForm = $_POST['fieldName']; // request data from the form
$soapUrl = "[login to view URL]"; // asmx URL of WSDL
$soapUser = "username"; // username
$soapPassword = "password"; // password
// xml post structure
$xml_post_string = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="[login to view URL]" xmlns:xsd="[login to view URL]" xmlns:soap="[login to view URL]">
<soap:Body>
<GetItemPrice xmlns="[login to view URL]"> // xmlns value to be set to your's WSDL URL
<PRICE>'.$dataFromTheForm.'</PRICE>
</GetItemPrice >
</soap:Body>
</soap:Envelope>'; // data from the form, e.g. some ID number
$headers = array(
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
"Cache-Control: no-cache",
"Pragma: no-cache",
"SOAPAction: [login to view URL]",
"Content-length: ".strlen($xml_post_s
