Sudah tentu, jika anda masih perlu menilai Android atau iOS, terdapat kaedah mudah Sesuaikan nilai HTTP_USER_AGENT pada bahagian mudah alih, dan kemudian dapatkan $_SERVER['HTTP_USER_AGENT'] daripada pelayan untuk menentukan sama ada watak ini adalah Wujud

$user_agent = $_SERVER['HTTP_USER_AGENT'];
            if (stripos($user_agent, 'my_webapp') !== false) {
                $this->assign("is_webapp", true);
        }
