PHP Content Management System (phpCMS) makes it possible to need only one template for your whole Web site. It allows you to provide dynamic menus with unlimited levels, and use templates and sub-templates without a database.

PHP code can be added to any template and content file with an optional module. It supports the caching of parsed pages and gzip compression.
