You can create a base controller with common vars and functions. All your controllers will inherit from it.

In application/libraries/MY_Controller.php

Code:

<?php
Class MY_Controller extends Controller {

    var $common_var;
    
    function MY_Controller()
    {
        parent::Controller();
    }
    
    function mult( $n1, $n2 )
    {
        return $n1 * $n2;
    }
}

In application/controllers/product.php

Code:

<?php

class Product extends MY_Controller {

    function Product()
    {
        parent::MY_Controller();
    }
    // ...
    // here you can use $this->mult()
}

Have a try and keep us updated.
