Constructor Problem

[eluser]marty123[/eluser]
Hi, I'm trying to implement my own library, there is an constructor like this one:

Code:

class Menu {
    
    function Menu()
    {
        $CI =& get_instance();  


    }

fucntion get_menu ($param){

$CI ->load->model('m_menu');
};
function three(){
...
}

But when I try to use $CI in functions, there is an error :


A PHP Error was encountered

Severity: Notice

Message: Undefined variable: CI

Filename: libraries/menu.php

Line Number: 29

I call my library this way:

Code:

$this->load->library('menu');
$menu1 = new Menu();
$error['menu'] = $menu1->get_menu('PL');

the solution is to add $CI =& get_instance();
in all functions in the class, but I thought it should take $CI from constructor, am I wrong?
