In what situations should the use of frames be reconsidered when working with PHP scripts?

The use of frames should be reconsidered when working with PHP scripts because frames can cause issues with search engine optimization, accessibility, and usability. Instead of using frames, consider using PHP includes to modularize your code and improve maintainability.

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