I have one controller named home.php in which a function named podetails is there. I want to call this function in another controller user.php.
Is it possible to do so? I have read about HMVC in CI, but I want to know is it possible to do without using hmvc?

我有一个名为 home.php 的控制器,其中一个名为 podetails的函数 在那里。 我想在另一个控制器 user.php 中调用此函数。
是否可以这样做? 我在CI中读过 HMVC ,但我想知道是否可以不使用hmvc?

    To extend controller please either follow this tutorial or see some code below.

    differences between private/public/protected

    make a file in folder /application/core/ named MY_Controller.php

    Within that file have some code like

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    class MY_Controller extends CI_Controller {
        protected $data = Array(); //protected variables goes here its declaration
        function __construct() {
            $this->output->enable_profiler(FALSE); // I keep this here so I dont have to manualy edit each controller to see profiler or not        
            $this->load->model('some_model'); //this can be also done in autoload...
            //load helpers and everything here like form_helper etc
        protected function protectedOne() {
        public function publicOne() {
        private function _privateOne() {
        protected function render($view_file) {
            if ($this->_is_admin()) $this->load->view('admin_menu_view');
            $this->load->view($view_file . '_view', $this->data); //note all my view files are named <name>_view.php
        private function _isAdmin() {
            return TRUE;

    and now in any of yours existing controllers just edit 1st or 2nd line where

    class <controller_name> extends MY_Controller {

    and you are done

    also note that all your variables that are meant to be used in view are in this variable (array) $this->data

    example of some controller that is extended by MY_Controller

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    class About extends MY_Controller {
        public function __construct() {
        public function index() {
            $this->data['today'] = date('Y-m-d'); //in view it will be $today;
            $this->render('page/about_us'); //calling common function declared in MY_Controller
    解决 无用
