PHP Soap - Consuming Web Service problems

Hi, This is the first time I have used PHP with SOAP as we have just upgraded our server to PHP5. I am trying to call the readChallenge method by consuming the PlayStream Web service. Here is the code I am using: // Define test vars $_POST['challenge'] = 'test 1'; define('P_GUID', 'test 2'); $client = new SoapClient( "http://www.playstream.com/license/DRMLicense.asmx?wsdl", array('trace'=>1) ); echo 'Dumping client object:'; echo "<pre>"; var_dump($client); echo "</pre>"; echo 'Dumping client object functions:'; echo "<pre>"; var_dump($client->__getFunctions()); echo "</pre>"; $readChallenge = $client->__soapCall( "readChallenge", array('null', $_POST['challenge'], P_GUID) ); echo '<pre>'; var_dump($readChallenge); echo '</pre>'; // Debugging echo "<hr><pre>\n"; echo "Request Headers:\n". htmlspecialchars($client->__getLastRequestHeaders()) ."\n"; echo "Request:\n". htmlspecialchars($client->__getLastRequest()) ."\n"; echo "Response Headers:\n". htmlspecialchars($client->__getLastResponseHeaders()) ."\n"; echo "Response:\n". htmlspecialchars($client->__getLastResponse())."\n"; echo "</pre>"; This gives no response apart from an empty array, any ideas what I am doing wrong? Many thanks.
