Create easy SOAP wrapper client for WSDL web service

We need to create a simple way to send ordering requests using the PHP soap client to post requests to our supplier's WSDL XML web service. The class should expose both the "getPreSubmitInfo" and "submitPO" web services, both require essentially the same information, but return different data. The class usage should ideally be simple like so: $class = new wsdlClass('getPreSubmitInfo'); $class->setParam1("somevalue"); $class->setParam2("somevalue"); $class->sendRequest(); Param1 and Param2 should be substituted for the appropriate parameter names. The class may be split into multiple classes if the winner deems it easier or more appropriate. Documentation of the services is attached to this project. Project should be delivered in a zip format.
