在MY_Controller Codeigniter 3中找不到变量配置

Question

I got error when I run this code

class MY_Controller extends CI_Controller {
    public function MY_Controller () {
        var_dump ( $this->config->item ('default_app') );
    }
}

Error:

Message: Undefined property: Welcome::$config

My MY_Controller is in Core folder & I use Codeigniter 3.0.6. The error tells that variable $config is not found.

Change

class MY_Controller extends CI_Controller
{
    public function MY_Controller()
    {
        var_dump ( $this->config->item('default_app') );
    }
}

with

class MY_Controller extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        var_dump ( $this->config->item('default_app') );
    }
}
