将代码应用于codeigniter中的所有控制器

Question

i have a simple code where i place it in my controller's constructor

$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");
$this->output->set_header("Pragma: no-cache");

i use this code for the safety of logout. my question is, Is there a way to put/declare my code as global for each of my controllers? because it will be hard to hard code everything on each controller's constructor.

Thank you for the help.

I like all the answers but the best approach is to use hooks. First Add this to your hooks.php

 $hook['display_override'] = array(
    'class'    => 'RouteProcess',
    'function' => 'afterroute',
    'filename' => 'RouteProcess.php',
    'filepath' => 'hooks',
    'params'   => array()
 );

Then go to hooks/ folder and create RoutesProcess.php Create the file below:

class RouteProcess{
function afterroute(){
    $this->CI =&get_instance();
     $this->CI->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");
    $this->CI->output->set_header("Pragma: no-cache");
    echo $this->CI->output->get_output();
}
}

The good thing about this is it does not require __construct() of your controller to be called which can be overridden. This will be called no matter what.
