What best practices should be followed to ensure that PHP pages are not stored in the browser cache?

To ensure that PHP pages are not stored in the browser cache, you can include specific headers in your PHP code to instruct the browser not to cache the page. This can be achieved by setting the cache-control and expires headers to prevent the browser from caching the page content. 

<?php
// Prevent caching of PHP page
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Expires: 0");
?>
