Unfortunately, it seems I can only get it to give me the line number of the PHP code from which I try to create the SOAP client, but no more details on the parsing problem.
Got it. If you google for the problem, lots of people have weird, unexplained problems parsing WSDL with PHP5’s native SOAP functionality. Can you use PEAR-SOAP? That’s part of DirectFlight’s test suite here at FlightAware and is a popular library that lots of other customers are using.
