What are the benefits of defining constants for file paths in PHP scripts to improve code readability and maintenance?

Defining constants for file paths in PHP scripts can improve code readability and maintenance by making it easier to identify and update file paths throughout the script. It also helps in avoiding hardcoding file paths multiple times, which reduces the risk of errors and makes the code more maintainable. 

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

// Example usage
include INCLUDE_PATH . 'header.php';
$config = include CONFIG_PATH . 'config.php';
?>
