What are the potential drawbacks of using iframes to integrate external content into a website?

Potential drawbacks of using iframes to integrate external content into a website include security risks such as cross-site scripting attacks, slower page load times, and issues with responsiveness on mobile devices.

<?php
// To avoid security risks associated with iframes, consider using server-side includes or APIs to integrate external content into your website.
// This way, you can control the content being displayed and mitigate the risk of cross-site scripting attacks.

include 'external_content.php';
