Are there any security considerations to keep in mind when using iframes in PHP?
When using iframes in PHP, it is important to prevent security vulnerabilities such as clickjacking. To mitigate this risk, you can set the X-Frame-Options header to deny or sameorigin in your PHP code. This will prevent your page from being embedded in an iframe on another domain.
<?php
header("X-Frame-Options: DENY");
?>
