What is the advantage of using the include command instead of manually reading individual files in PHP?

Using the include command in PHP allows for easier management and organization of code by allowing you to include external files without having to manually read each one. This can help reduce redundancy, improve code readability, and make it easier to maintain and update your code in the future.

<?php
include 'file1.php';
include 'file2.php';
include 'file3.php';
?>
