php - How to build in 'maintenance mode' in Codeigniter?

I'm using latest codeigniter and I need to create a flag (ideally in the config) when turned to 'true', all pages display a 'maintenance mode' message instead of executing their controller code.

What is the best/simplest practice for doing this?

Here my solution, works fine for me:

The below will call maintanance.php immediately, so you can go ahead and break your CI code without the world seeing it.

Also allow you to add you own ip address so that you can still access the site for testing etc.

In index.php add at top:

$maintenance = false; ## set to true to enable

if ($maintenance)
{
    if (isset( $_SERVER['REMOTE_ADDR']) and $_SERVER['REMOTE_ADDR'] == 'your_ip')
    {
        ##do nothing
    } else
    {

        error_reporting(E_ALL);
        ini_set('display_errors', 1); ## to debug your maintenance view

        require_once 'maintenance.php'; ## call view
        return;
        exit();

    }
}

Add file Maintanance.php in same folder as index.php (or update path above):

<!DOCTYPE html>

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Maintenance</title>

        <style>
            body {
                width:500px;
                margin:0 auto;
                text-align: center;
                color:blue;
            }
        </style>
    </head>

    <body>

        <img src="images/home_page_logo.png">

        <h1><p>Sorry for the inconvenience while we are upgrading. </p>
            <p>Please revisit shortly</p>
        </h1>
        <div></div>

        <img src="images/under-maintenance.gif"   >

    </body>
</html>
<?php
header('HTTP/1.1 503 Service Temporarily Unavailable');
header('Status: 503 Service Temporarily Unavailable');
header('Retry-After: 3600');
?>
