soapserver.php



<?php

ini_set("soap.wsdl_cache_enabled", "0"); 

class service

{

    public function HelloWorld() {

      return  "Hello";

    }

    public  function Add($a,$b) {

      return $a+$b;

    }

}

$server=new SoapServer('TestSoap.wsdl',array('soap_version' => SOAP_1_2));

$server->setClass("service");

$server->handle();

?>

serviceclient.php



<?php

try {

$client=new SoapClient("http://localhost/soapService/TestSoap.wsdl");

echo $client->HelloWorld();

echo("<br />");

print_r($client->Add(1,2));

}

    catch ( SoapFault $e ) { echo $e->getMessage (); }

    catch ( Exception $e ) { echo $e->getMessage (); }

?>

TestSoap.wsdl

请各位老师指教。
