Can I use SoapClient without wsdl to connect to a web service (SoapServer) that was created with wsdl?

Question

PHP

Is it possible to create a SoapClient without a wsdl to request a SoapServer that was created with a wsdl
SOAP client

$client = new SoapClient(null, array(
    'location'=>'http://localhost/webService',
    'uri'=>'targetNameSpace',
    'trace' => 1
 ));

SOAP server
$server = new SoapServer("myfile.wsdl");
If possible, why is this webservice not working? gives Procedure not present exception.
Here is the web service code

Answer 1

The client does not need its own wsdl. The client uses the one on the server to find out what the server is and how to communicate with it.
