php实现发送url到指定的客户端


     $type=$_GET["servicetype"];     switch($type){
            case "install":
                header("location:../installandappointmentsetting.php?type=ins&number=$phone");
                break;
            case "appointment":
                header("location:../installandappointmentsetting.php?type=app&number=$phone");
                break;
         }当客户端A登录后，客户端B传递servicetype参数给存放在服务器的以上代码段，服务器接收到该参数，判断后，怎样将
../installandappointmentsetting.php?type=ins&number=$phone这个url发送给客户端A?
请大侠赐教!!!谢谢
