How can PHP developers ensure that their websites comply with privacy regulations and protect user data when incorporating external content like iframes?

When incorporating external content like iframes, PHP developers can ensure compliance with privacy regulations and protect user data by implementing Content Security Policy (CSP) headers. By setting specific directives in the CSP headers, developers can control which external sources are allowed to load content on their website, reducing the risk of malicious code injection and unauthorized data access. 

<?php
header("Content-Security-Policy: frame-ancestors 'self'; frame-src https://trusted-external-source.com;");
?>
