How to have a copyright date automatically generated by PHP

A sure sign of a site that isn't actively maintained is an out-of-date copyright date.

The easiest way to avoid this is by having the current inserted by php code. I use NoNumber's sourcer extension to allow me to insert php code into a module.

Copyright &copy;&nbsp;<?php echo date('Y'); ?> &nbsp;<?php echo htmlspecialchars($app->getCfg('sitename')); ?>
