I have been breaking my head at this, reading almost every article and tutorial there is on the web, but nothing doing.. i still cannot get my first web service application to work.

I would really appreciate it if anyone could debug this code for me and provide me with a good explanation as to what is wrong and why. This will help indeed ! Thanks !

I have pasted below the entire codes that i am using making it easier to debug. I'm using the PHP5 SOAP extension.

Here is my WSDL:

    <?xml version="1.0" encoding="utf-8"?>

    </wsdl:port>
  </wsdl:service>

</wsdl:definitions>

and here is the PHP Code i use to setup the server:

<?php

    function getUser($user,$pass) {
        return array('ID'=>1);
    }

    ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
    $server = new SoapServer("http://127.0.0.1/mywsdl.wsdl");
    $server->addFunction('getUser');
    $server->handle();

?> 

and the code for the client:

<?php

    $client = new SoapClient("http://127.0.0.1/index.php?wsdl", array('exceptions' => 0));

    try {
        $result = $client->getUser("username","pass");
        print_r($result);
    }
    catch (SoapFault $result) {
        print_r($result);
    }

?> 

Here is the ERROR output i am getting on the browser :
