What are the potential issues with using iframes in PHP web development?
Potential issues with using iframes in PHP web development include security vulnerabilities such as clickjacking, where an attacker can trick a user into interacting with the iframe unknowingly. To prevent this, it is recommended to use the X-Frame-Options header to control if and how a page can be embedded in an iframe.
<?php
header("X-Frame-Options: DENY");
?>
