我在/ application / core中有一个控制器

/application/core/CMS_Controller.PHP

@H_126_3@<?PHP if ( ! defined('BASEPATH')) exIT('No direct script access Allowed'); require APPPATH."third_party/MX/Controller.PHP"; class CMS_Controller extends MX_Controller { public function __construct() { parent::__construct(); } public function show_something() { echo "something shown"; } }

我在模块中有另一个控制器(/modules/my_module/controllers/controller.PHP),它从CMS_Controller扩展而来

/modules/my_module/controllers/controller.PHP

<?PHP if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Controller extends CMS_Controller {

    public function index() {
        $this->load->view('view');
    }
}

并且,在view.PHP(/modules/my_module/views/view.PHP)中我这样做：
/modules/my_module/views/view.PHP

<?PHP if ( ! defined('BASEPATH')) exit('No direct script access allowed');
 $ci =&amp; get_instance();
 echo $ci->show_something();
?>

我收到这个错误：

如果我不使用MX_Controller并使用CI_Controller,它将起作用：
/application/core/CMS_Controller.PHP

<?PHP if ( ! defined('BASEPATH')) exit('No direct script access allowed');

//require APPPATH."third_party/MX/Controller.PHP";

class CMS_Controller extends CI_Controller {

    public function __construct() {
        parent::__construct();
    }

    public function show_something() {
        echo "something shown";
    }
}

谁知道这里有什么问题？

/* allow CI_Controller to reference MX_Controller */
CI::$APP->controller = $this;

$this->CI =& get_instance();

$this->CI =& get_instance()->controller;
