It is undoubtedly one of the most asked questions on the PHP mailing lists: how doI make my PHP scripts independent of the layout? While PHP is billed as "HTMLembedded scripting language", after writing a couple of projects that mixed PHPand HTML freely one comes up with the idea that separation of form and content isa Good Thing [TM]. In addition, in many companies the roles of layout designer andprogrammer are separate. Consequently, the search for a templating solution ensues. In our company for example, the development of an application goes on as follows:After the requirements docs are done, the interface designer makes mockups of theinterface and gives them to the programmer. The programmer implements businesslogic in PHP and uses interface mockups to create skeleton templates. The projectis then handed off to the HTML designer/web page layout person who brings thetemplates up to their full glory. The project may go back and forth between program-ming/HTML a couple of times. Thus, it’s important to have good template supportbecause programmers don’t want anything to do with HTML and don’t want HTMLdesigners mucking around with PHP code. Designers need support for config files,dynamic blocks and other interface issues, but they don’t want to have to deal withintricacies of the PHP programming language.
