Are there any alternative methods to ensure that PHP pages are always reloaded for all users?

One alternative method to ensure that PHP pages are always reloaded for all users is to add a random query string to the end of the URL. This will force the browser to fetch a fresh copy of the page each time, bypassing any caching mechanisms. 

<a href="page.php?<?php echo uniqid(); ?>">Reload Page</a>
