If you’re still wondering about the difference between WordPress actions and WordPress filters, Michael Fields posted a very cool explanation in this forum thread called Actions vs. Filters. I think it’s the best explanation of actions and filters I have seen so far, well done Michael, and keep up the good work!

Let’s pretend that WordPress is a Mexican restaurant and we have ordered a taco as illustrated by the following code… <?php $taco = 'chicken'; ?>

Hat tip to Philip for finding this little two-year old treasure in the forums. If you’re interested in a very detailed article about the internals of actions and filters, check out Gennady’s post called Inside WordPress Actions and Filters.
