I am trying to develop webservice in php using ws02 php webservice framework.
I am using this framework along with WAMP server.Here is my sample server code

Code:
<?php
/*** operation add
* @param int $x operand1 <- This is the PHP type
* maps to xs:int <- This is the schema type
* @param int $y operand2 <- This is the PHP type
* maps to xs:int <- This is the schema type
* @return int $result
*/
function add($x, $y)
{   
return array("result" => $x + $y);
}
$operations = array("add" => "add");
$opParams = array("add" => "MIXED");
$svr = new WSService(array("operations" => $operations,"opParams" => $opParams,"serviceName" => "Calculator"));
$svr->reply();
?>
client code
Code:
<?php 
try {
 
    // create client in WSDL mode
    $client = new WSClient(array ("to" =>"http://localhost/calculator.php")); 
 
    // get proxy object reference form client 
    $proxy = $client->getProxy();
    $x=5;
    $y=3;
    $response=$proxy->add($x,$y);
    echo $response;
 
    // create input object and set values
} catch (Exception $e) {
    // in case of an error, process the fault
    if ($e instanceof WSFault) {
        printf("Soap Fault: %s\n", $e->Reason);
    } else {
        printf("Message = %s\n", $e->getMessage());
    }
}
?>
Problem is on the client side I get no response at all.Has anybody worked on this before?Can you please kindly help me in figuring out what the problem is?

Thanks in advance
