Smarty is a template engine for PHP. Smarty separates PHP code and business logic, HTML code, and 
presentation logic, and generates web content by the placement of Smarty tags within a document. It is under the LGPL license so it can be used freely.
It is common in large projects the role of graphic designer and programmer are covered by different people, but the PHP programming tends to combine these two tasks in a person within the same code which brings great difficulties When replacing any part of the design of the page, then you have to dig into scripts to modify the presentation of content, Smarty seeks to solve this problem. - Wikipedia
