php关于请求webservice的有关问题，请版主帮忙

$url = 'http://b2b.ourgame.com/DDService.asmx?wsdl';
$soapClient = new soapclient($url);

/* 读取可用的方法和所需的数据结构 */
print_r( $soapClient->__getFunctions ()); 
print_r($soapClient->__getTypes () ); 

$rs = $soapClient->Sale();
print_r($rs);

------解决方案--------------------
PHP code

ini_set("soap.wsdl_cache_enabled",0);
    try{
        $client = new SoapClient("http://b2b.ourgame.com/DDService.asmx",array("exceptions" => 1));
        
        var_dump($client->Sale(array("arg0"=>1,"arg1"=>"123","arg2"=>"456","arg3"=>"789","arg4"=>4,"arg5"=>5,"arg6"=>"111","arg7"=>"222")));
    }catch(Exception $ex){
        var_dump($ex->faultstring);
    }
