        $sn = $client->getstatusBysn(array('smn'=>$sn));

        $pd=0;

        if($sn->getstatusBysnResult  === true){

            $pd=1;

        }else if($sn->getstatusBysnResult  === false){

            $pd=0;

        }else{

            $pd=0;

//            echo "未知".$sn->getstatusBysnResult;

        }

    }catch (SoapFault $e){

        $pd=0;

//        echo "未知".$sn->getstatusBysnResult;

    }

    return $pd;

}
