Description:
------------
I have written a simple Hello World client/server application.

When I issue my request, no exception is thrown, but the result is NULL, even though the SOAP response suggests it should be otherwise.

Reproduce code:
---------------
Server:

<?php

class hello_world {
   
    /**
     * Say Hello to Somebody
     *
     * @param string $to The person to say Hello to
     * @return string The greeting
     */ 
     
    public function hello($to)
    {
        return $this->constructMsg($to);
    }
    
    public function goodBye($to)
    {
        return "Goodbye $to";
    }
    
    /**
     * Construct Greeting
     *
     * @param string $to
     * @return string
     */
    
    private function constructMsg($to)
    {
        return 'Hello ' . $to;
    }    
}

$server = new SoapServer('HelloWorld.wsdl', array('trace' => 1));
$server->setClass('hello_world');

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $server->handle();
} else {
  echo "This SOAP server can handle following functions: <br />";
  $functions = $server->getFunctions();
  foreach($functions as $func) {
   echo $func . "<br />";
  }
}

?>

Client:

<?php

$client = new SoapClient('http://davey.synapticmedia.net/php-mag/shafikdavey_automaticwebservices/src/HelloWorld.wsdl', array('trace' => 1));

try {
    echo $client->hello('davey');
    echo $client->__getLastRequestHeaders();
    echo "\n";
    echo "\n";
    echo $client->__getLastRequest();
    echo "\n";
    echo "\n";
    echo $client->__getLastResponse();
}
catch (Exception $e) {
    echo $e;
    echo "\n";
    echo "\n";
    echo $client->__getLastRequestHeaders();
    echo "\n";
    echo "\n";
    echo $client->__getLastRequest();
    echo "\n";echo "\n";
    echo $client->__getLastResponse();
}

?>

Expected result:
----------------
"Hello davey"

Actual result:
--------------
returns NULL
