Building web aplications that split out the responsibilities correctly is becoming more and more important. Developers are creating more complex applications, and cluttering up the presentation with the logic of the code can only make things more of a nightmare down the road. Thankfully, there are articles like this one from DevShed to help you template your site correctly.
This is the first part of a three-part series that covers separating logic from presentation in PHP applications. In this article you will learn to develop a template system that is advanced enough to meet the requirements of a majority of applications.
It's possible to develop an intermediate template system that meets the requirements of a vast majority of applications, without the need to appeal to basic packages or having to deal with the numerous features of Smarty. It's precisely for this reason that this series will be focused on developing an extensible template processor in PHP 5.
You'll need a bit of experience with templating your site before you get started, as they begin with a basic structure of the template processor before anything. They demonstrate the code to create the "TemplateProcessor" class and defining the "processTemplate" method inside it. By the end of this first part in the series, they've created a very simple templating class that could be used as is for base-level projects. Stay tuned for more, though, if you're hungry for more features.
