PHP to use WSDL from local Windows Service

I have a windows service stored locally on my computer. The services are specified through an WSDL interface. How can I access these methods from the local stored windows service on my website through PHP?

I looked and looked but can't find any documentation on how to use PHP with WSDL.

I'm not sure I understood this whole cycle correct as well. As I understand it:

I have a local stored windows service. It has some methods, which are accessible through WSDL for web purpose. I can then use PHP to work with WSDL to access these methods and use them on my website.

Is this understood correct?

This is the part of my wsdl I want to access: <wsdl:operation name="GetStudyData"> <wsdl:input wsaw:Action="" message="tns:IKPIntegrationServices_GetStudyData_InputMessage"/> <wsdl:output wsaw:Action="" message="tns:IKPIntegrationServices_GetStudyData_OutputMessage"/> </wsdl:operation>

I want to show this data that comes from "GetStudyData" on my webpage through php somehow.
