Web services test

Hey all.
I’m trying to build an application which will consume Web Services which were created in PHP5. I’m finding that there is no easy way to test and make sure everything is working properly.

Does anyone know of a flash tool (or similar idea) that would allow me to:

a) Check the syntax of my wsdl file to make sure everything’s cool.
b) Allow me to call the methods of the web service and pass parameters which are created on the fly and then dump the results of my call.

I’m basically looking for some sort of tool that will help me to test every wsdl and method that I am developing.

Oh… and of course, it spits out any errors that occur in the process.
