PHP call to Workday SOAP Webservice through WSDL URL

Question

I am trying to call SOAP webservice for which WSDL file is already given. I am able to test these SOAP Request and Response through SOAP UI or Chrome Boomerang. I am able to get response properly.

Client has shared WSDL URL, Username, and Password. How can I use PHP code to call services. My concern is that I have request and response in XML format.

Can I send XML directly in the request. How could I make a SOAP Request with these given XML-Request information. Do I need to parse into objects or arrays. Thanks in advance.

XML Request that sends me response on SOAP UI is -

<?xml version="1.0" encoding="UTF-8"?>
