How to work with SOAP, WSDL?

Question

PHP

I'm trying to call the method described in the wsdl document and I'm getting an infinite redirect error. I mean that one of the parameters was incorrectly passed or the type was not taken into account, but I can’t debug anything, no details, just a browser error message. And the document itself and the methods described in it are like a dark forest, I can’t understand anything.

For debugging requests, I recommend www.soapui.org
Very easy to use, eats wsdl and builds requests - you just need to drive in the parameters. Once you get the result, you can peek at the request code and get the same xml package from your script.
