extending the controller

It's CI_Controller not Controller for CodeIgniter 3.
CodeIgniter 4 uses Controller.

PHP Code:

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

class MY_Controller extends CI_Controller
{
    function __construct()
    {
        parent::__construct();
    }
}
