Pipit: pipit_version()

Adds the last modified time of a file for easier browser cache busting.

To add the last modified time as a query string (default):

<script src="<?php echo pipit_version('/js/app.js'); ?>"></script>

Output:

<script src="/js/app.js?v=1511342726"></script>

To add the last modified time as part of the file’s name you need to set the second argument to name:

<script src="<?php echo pipit_version('/js/app.js', 'name'); ?>"></script>

Output:

<script src="/js/app.1511342726.js"></script>

And you’ll need to add the following .htaccess rules:

RewriteRule ^(.+)\.(\d+)\.(js|css)$ $1.$3 [L]
