WSF/PHP with doc-lit bare WSDLs

You may use doc-lit bare WSDL to send a web service request with just one simple parameter in the message, like this.

<echoInt>3</echoInt>

In order to prepare this message with wsdl mode in WSF/PHP you can directly input the parameter value without instantiate any wrapper classes. Just take look at the following doc-lit bare WSDL and the corresponding WSDL-mode client to have an idea how easy it is.

      <wsdl:input message="ns0:echoIntRequest" wsaw:Action="urn:echoInt"/>
      <wsdl:output message="ns0:echoIntResponse" wsaw:Action="urn:echoIntResponse"/>

  </wsdl:operation>
</wsdl:portType>
<wsdl:binding name="EchoServiceSOAP12Binding" type="ns0:EchoServicePortType">

  <soap12:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
  <wsdl:operation name="echoInt">

      <soap12:operation soapAction="urn:echoInt" style="document"/>
      <wsdl:input>
          <soap12:body use="literal"/>

      </wsdl:input>
      <wsdl:output>
          <soap12:body use="literal"/>
      </wsdl:output>

  </wsdl:operation>

<wsdl:service name="EchoService">
  <wsdl:port name="EchoServiceSOAP12port_http" binding="ns0:EchoServiceSOAP12Binding">

      <soap:address location="http://localhost:8080/dyn/codegen/demo/services/EchoService"/>
  </wsdl:port>
</wsdl:service>
</wsdl:definitions>

And the client is simple as this

// the background work for create wsclient and the proxy
$client = new WSClient(array ("wsdl" =>"echo.wsdl"));

$proxy = $client->getProxy();

// you directly input the request parameter
$response = $proxy->echoInt(3);


echo $response;

So in a case where you just need to send only one parameter for the service operation, this form of messages make your web service call more efficient and more easy to implement.
