How can PHP variables be effectively used to manage different versions of index.php files in a CMS?

To manage different versions of index.php files in a CMS using PHP variables, you can create a variable that stores the version number and use conditional statements to load the appropriate version of the file based on the value of the variable. This allows for easy maintenance and updates without having to manually change file names or paths. 

<?php
$version = 2;

if ($version == 1) {
    include 'index_v1.php';
} elseif ($version == 2) {
    include 'index_v2.php';
} else {
    include 'index_default.php';
}
?>
