How can PHP include functions be utilized to create a dynamic website layout without frames?

To create a dynamic website layout without frames using PHP include functions, we can break down the different sections of the website into separate files (header, footer, sidebar, content, etc.) and then use PHP include functions to pull these sections into a single PHP file. This allows for easier maintenance and updates as each section is modular and can be edited independently.

<?php
include 'header.php';
include 'sidebar.php';
include 'content.php';
include 'footer.php';
?>
