codeigniter中的全局控制器?

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->select('*');

  $this->db->from('users');
  $this->db->order_by('id', 'DESC'); 
  $this->db->limit('5');

  $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

在codeigniter中有一种方法可以定义一个可以在所有控制器中轻松调用的全局函数吗?

我有一个应用程序,将显示已在应用程序上注册的所有最新用户。

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();  
 
} 
   
 
 

在所有控制器上,我在开始时调用此模型

  $  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 。

那么实现这一目标的最佳方法是什么?

任何帮助将不胜感激

    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() {
            parent::__construct();
    
            $this->data['new'] = $this->Latest_model->new_users();
        }
    }
    

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