A theme engine that allows you to use template files written in pure php. These template files do not need to be processed by the theme engine, and as such execute a lot faster than most other template engines. Another major advantage to using PHP as your template language, is flexibility, as the advanced user can access any information / functionality available in the Drupal API, and is not restricted to what the template engine / language allows him to do.
The template engine’s job is to help separate out application model logic from display logic and to provide a simpler, more readable way to add functionality to your display files. Since HTML was never meant to handle arbitrary logic, it is generally kept separate from the Model and Controller layers of an application.
