PHP-Nuke is a web-based automated news publishing and content management system based on PHP and MySQL originally written by Francisco Burzi. The system is controlled using a web-based user interface. PHP-Nuke was originally a fork of the Thatware news portal system by David Norman.
PHP-Nuke was originally released under the GNU General Public License as free software. Versions after 7.5 required a license fee; from version 8.3 it became free again. This is permitted under the GNU GPL (providing the source code is included), and the purchaser of the software has the right to freely distribute the source code of the product. Burzi no longer owns the PHP-Nuke site.
As of version 5.6, the display of a copyright message on webpages is required in accordance with the GPL section 2(c).PHP-Nuke requires a web server which supports the PHP extension, as well as an SQL database.
