A previous developer has a working successful SOAP call using nusoap. I am trying to make another web service call to the same service. I constructed the XML (in text) and verified with the service provider that it is the correct XML. I placed the same XML in a variable ($param = '...';). I made the call using $client->call('MethodName', $param); This call is not even getting to the provider. I am getting an 'Object reference not set...' error. I am using the Zend framework.
Am I not sending XML correctly? Where could the problem be?
Should I use any other libraries instead of nusoap?
