What are some practical solutions to prevent pages from being loaded from the browser cache in PHP?

To prevent pages from being loaded from the browser cache in PHP, you can add cache-control headers to your PHP script. This will instruct the browser not to cache the page and always request a fresh copy from the server. You can achieve this by setting the cache-control header to 'no-cache' and adding additional headers to ensure the page is not cached. 

<?php
// Prevent pages from being loaded from the browser cache
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
header("Expires: 0");
?>
