The architecture of PHP-Nuke, with its modules, blocks, topics and themes is presented in detail, as well as the interplay of PHP and MySQL for the creation of a mighty content management system (CMS).It also delves into more advanced issues, like the programming of PHP-Nuke blocks and modules, security, acceleration, and optimization.
