PHP-Nuke is a free, web-based, automated news publishing and CMS based on PHP (a computer programming language, originally designed for producing dynamic web pages) and MySQL (a multithreaded, multi-user SQL database management. The basic program runs as a server providing multi-user access to a number of databases. An SQL is a database computer language designed for the retrieval and management of data).
PHP-Nuke requires a web server which supports the PHP extension as well as an SQL. Its main aim is to allow you to create a community-based portal with an automated website allowing users and editors to post new items. Modules may be added to the PHP-Nuke system, allowing you to add more features to your PHP-Nuke installation in addition to the core modules such as News, FAQ, and Private Messaging. The whole system is maintained by administrators using the web-based administration section.
PHP-Nuke is designed to be very customizable and flexible, as well as easy and pleasant to use. It comes with English set as the default language, but you can change it to your own language. There are more than 20 languages supported. PHP-Nuke also offers a very high number of features that are not present on other systems, and on each release new features are added.
