比如：
namespace Common\Common;
use Think\Controller;
abstract class AController extends Controller{
function __construct(){}
abstract function isLogin();
}
namespace Home\Common;
use Common\Common\AController;
class FController extends AController{
function __construct(){
parent::__construct();
}
function isLogin(){
$user_id = session('user_id');
if(isset($user_id)){
return true;
}
return false;
}
}
namespace Home\Controller;
use Home\Common\FController;
class DefaultController extends FController {
function index(){
$this->display(); // 这里出错
}
}
