Invalidate Smarty Cache Using Cache Dependency Files

Smarty is perhaps the most powerful and widely used PHP template engine available for PHP-based application developments. Though its usage has now been a bit pulled-aside by the rise of more advance frameworks such as Drupal or CakePHP, which come with their own template system implementations, for a "bare" template engine Smarty is still the favorite. I myself still use the combination of Smarty and PEAR (PHP Extension and Application Repository) for most of my PHP projects.

Taking it more than just a template engine, Smarty provides a built-in caching functionality. Smarty caches the server response, and that is in pure HTML. This is nice in the term of performance, especially for an extensive script-processing generated page (ie. script that does several database queries). As long as the cache hasn't been invalidated, in subsequent request of the page Smarty will simply return the pure HTML cache instead of executing the script every time.
