Soap problems connecting to .NET server

[deathcomp]

So we are just starting to learn how to use soap with php. So I'm pretty new with this. We decided to consume a simple stock quote web service to start with because it was very simple. However, we are getting an error and from what I read it's a problem with php/soap talking to .NET soap servers. Anyone get this error and figure out a solution?

Code: Select all

<?php

$wsdl = "http://www.restfulwebservices.net/wcf/StockQuoteService.svc?wsdl";
$endpoint = "http://www.restfulwebservices.net/wcf/StockQuoteService.svc";
$client = new SoapClient($wsdl, array('location'=>$endpoint,
                              'trace'=>1,
                               'exceptions'=>0));

$value = $client->GetStockQuote('IBM');

print "<pre>\n";

print "<br />\n Request : ".htmlspecialchars($client->__getLastRequest());

print "<br />\n Response: ".htmlspecialchars($client->__getLastResponse());

print "</pre>";



?>

Here's the output:

Code: Select all

For testing purposes we installed soapui to test this as well. It works just fine when we put 'IBM' in the request. However it's also a .NET client.

Any help would be greatly appreciated.

Actually SoapUI is Java program, not .NET.

About your actual problem, I'm not sure about the cause of that, but when I was starting out with SOAP Web Services and I had problems with getting everything right agains .NET services/clients I went with NuSOAP toolkit because regular PHP Soap didn't seem to work very well in those situations.

Maybe you should try it out:
