How can constants be utilized to define file paths in PHP scripts for improved maintainability?

Using constants to define file paths in PHP scripts can improve maintainability by centralizing the paths in one location. This makes it easier to update paths if they change in the future, as you only need to update the constant value in one place rather than searching through the entire codebase. Additionally, constants provide a clear and descriptive way to reference file paths throughout your scripts.

php 
<?php

define('INCLUDE_PATH', '/path/to/includes/');
define('CONFIG_PATH', '/path/to/config/');

include(INCLUDE_PATH . 'header.php');
include(CONFIG_PATH . 'database.php');

?>
