If you've been working on a site, and the pages are starting to get a bit out of hand as far as templating, there's plenty of systems out there that can help you get things back under control. Thanks to Zend, you can get started with Smarty and tame that site.

Be aware, this tutorial isn't for the timid or the new to Smarty. You'll want to have a good grasp of how their system works, and have it somewhat working with your site to get these advanced features working. They show you a few things, including: extending the Smarty classes, securing Smarty, and data manipulation within the Smarty templates.

This is a pretty good summary of some of the more advanced features in this powerful templating system, but this isn't all of them - it's just the beginning. For more info, check out the Smarty homepage.
