PHP访问webservices

I am trying to access this web service and it is working fine but when i come to diplay the results using the TopGoalScorersResult it is giving me this error "Catchable fatal error: Object of class stdClass could not be converted to string". Can anyone please help me with this. The $results variable is filled with the correct answers just want to display them using the method TopGoalScorersResult

<?php
 try {
  $client = new SoapClient(
  'http://footballpool.dataaccess.eu/data/info.wso?wsdl');
   var_dump($client->__getFunctions());
   var_dump($client->__getTypes());
   $results = $client->TopGoalScorers(array("iTopN"=>"20"));
   var_dump($results);

   echo $results->TopGoalScorersResult;

 } catch (SoapFault$e) {
     echo "<pre>" . $e->getMessage() . "</pre>";
    } 
     ?>

web services in php4 you can use SOAP on the WSDL to call the web-service functions exmaple link is hereenter link description here

$client = new SoapClient("youridSome.wsdl");

and now $client is now an object . There was a method called getTime() in the WSDL then you use

$result = $client->getTime();
