        $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;
}
