PHP-Nuke is a web-based automated news publishing and content management system based on PHP and MySQL originally written by Francisco Burzi.

PHP-Nuke was originally a fork of the Thatware news portal system by David Norman.

PHP-Nuke is a content management system allowing webmasters to create community-based portals (websites), allowing users and editors to post news items (user-submitted news items are selected by editors) or other types of articles.

Modules can be added to the PHP-Nuke system allowing additional features such as an Internet forum, Calendar, News Feed, FAQs, Private Messaging and others.

Several security holes have been discovered in PHP-Nuke, including SQL injection via unchecked PHP code.
