php使用soap的例子

<?php 
class service 
{ 
  public function HelloWorld() 
   { 
      return  "Hello"; 
   } 
  public  function Add($a,$b) 
   { 
      return $a+$b; 
   } 
} 
$server=new SoapServer(null,array('uri' => "abcd")); 
$server->setClass("service"); 
$server->handle(); 
?> 

<?php 
try{ 
$soap = new SoapClient(null,array( 
"location" => "http://localhost/interface/soap.php", 
"uri"      => "abcd",  //资源描述符服务器和客户端必须对应 
"style"    => SOAP_RPC, 
"use"      => SOAP_ENCODED 
   )); 

echo $soap->Add(1,2); 
}catch(Exction $e){ 
echo print_r($e->getMessage(),true); 
} 
?>
