To automate the integration of HTML files into a website layout without using frames, PHP can be utilized to include the contents of the HTML files within the desired webpage. This can be achieved by using the PHP include() function to dynamically insert the HTML files into the layout template, allowing for easy management and updating of the website content.

<?php
include('header.html'); // Include header HTML file
include('content.html'); // Include content HTML file
include('footer.html'); // Include footer HTML file
?>
