Answer 1

It appears that the PHP SOAP client is throwing a SoapFault, but you're not catching it in a try/catch block.

The SoapFault appears to be thrown because the other end of the web service has an unhandled exception in its code... the stack trace being shown is actually from the .NET service on the other end.
