Are frames a viable solution for hiding query parameters in the URL in PHP applications, or are there better alternatives?

One way to hide query parameters in the URL in PHP applications is to use frames. By loading the sensitive content within a frame, the query parameters will not be visible in the main URL. However, frames have limitations and may not be the most secure solution. A better alternative would be to use server-side processing to handle sensitive data and avoid passing it through query parameters.

<!-- index.php -->
<!DOCTYPE html>
<html>
<head>
    <title>Hidden Query Parameters</title>
</head>
<body>
    <iframe src="hidden_content.php"></iframe>
</body>
</html>

<!-- hidden_content.php -->
<?php
// Your sensitive content and processing logic here
?>
