Was sind mögliche Probleme bei der Verwendung von iframe in PHP für den Aufbau einer Webseite?

Possible problems when using iframes in PHP for building a website include security vulnerabilities such as cross-site scripting (XSS) attacks, issues with responsive design, and difficulties in maintaining and updating content within the iframe. To mitigate these problems, it is important to sanitize user input, ensure that the iframe is responsive to different screen sizes, and regularly check for outdated or broken content within the iframe. 

<?php
// Sanitize user input before using it in the iframe
$iframe_url = filter_var($_POST['iframe_url'], FILTER_SANITIZE_URL);
?>

<iframe src="<?php echo $iframe_url; ?>" width="100%" height="500"></iframe>
