How can PHP developers test and troubleshoot the functionality of embedding .htaccess-protected content in iframes locally?

To test and troubleshoot the functionality of embedding .htaccess-protected content in iframes locally, PHP developers can create a proxy script that fetches the protected content and serves it within the iframe. This way, the .htaccess protection is bypassed, allowing for easier testing and troubleshooting.

<?php
$url = 'https://example.com/protected-content.html';
$content = file_get_contents($url);
echo $content;
?>
