PHP-Nuke is a web-based automated news publishing and content management system based on PHP and MySQL. The system is fully controlled using a web-based user interface. PHP-Nuke was originally a fork of the Thatware news portal system.

PHP-Nuke was originally released under the GNU General Public License as free software however, versions after 7.5, are pay for use.

PHP-Nuke is a content management system allowing webmasters to create community-based portals (websites), in which users and editors can post news items (user-submitted news items are selected by editors) or other types of articles. Registered users can then comment on these articles using a full featured commenting system.

Modules can be added to the PHP-Nuke system allowing additional features such as an Internet forum, Calendar, News Feed, FAQ's , Private Messaging and others. The site is maintained through an administration section.

PHP-Nuke includes the following standard modules:

• Advertising—Manages ads on the page layout (theme). Supports images/links, javacript/HTML, and flash
• Avantgo—Provides mobile version of the last 10 news articles
