Is there a way in codeigniter to define a global function that can be called in all controllers easily?

I have a application that will show all latest users who have registered on the app.

what im doing now is, i have autoloaded a model Latest_model with the below function

function new_users()

  $this->db->order_by('id', 'DESC'); 

  $query = $this->db->get();
  return $query->result_array();


and on all the controllers, at the beginning i call this model

$data['new'] = $this->Latest_model->new_users();

It works but, i need to repeat this in all the functions.

So what would be the best way to achieve this?

Any help will be appreciated

我现在正在做什么,我已经自动加载了模型 Latest_model 使用以下函数

  function new_users()
 $ this-> db-> select('*'); 
 \  n $ this-> db-> from('users'); 
 $ this-> db-> order_by('id','DESC');  
 $ this-> db-> limit('5'); 
 $ query = $ this-> db-> get(); 
 return $ query-> result_array();  


  $  data ['new'] = $ this-> Latest_model-> new_users(); 

它有效,但我需要在所有函数中重复这一点 。

    You can always extend default controller with new functionality. Codeigniter's documentation is the good place to start.

    In short you should create your base controller named MY_Controller under application/core/ folder. Then you can place inside this file some code like this:

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    class MY_Controller extends CI_Controller {
        protected $data = [];
        function __construct() {
            $this->data['new'] = $this->Latest_model->new_users();

    Then from all your controllers you can access the data array with $this->data.
