What are the advantages and disadvantages of including pages in PHP versus using a different approach for navigation structures?

When including pages in PHP for navigation structures, the advantages include easier maintenance and updating of the navigation menu across multiple pages. It also allows for dynamic content based on user interactions. However, the disadvantages may include slower loading times for the website due to server-side processing for each page request.

<?php
// Navigation menu included in a separate PHP file
include 'navigation.php';
?>
