Test whether SOAP is running properly

Programatically, I want to test whether SOAP is working f开发者_StackOverflow中文版ine on my clients machine. The machine can be windows/linux. I want to get the SOAP version as well. I'm using PHP.

Similarly, I want to do it for WS02/WSF.

Thanks.

Set up a SOAP server and run a test script against it. If the test script works, SOAP on the client works.
