Summary

phpBB is free, open-source software for building online forums. It is self-hosted as a web application, so running it requires a PHP web server and a supported SQL database. For phpBB 3.3, the server needs PHP 7.2 or later; listed database systems include MySQL, MariaDB, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle. Board features can be adjusted in an administration panel without directly editing code. Community-built extensions can add features, while styles change a board’s appearance. The default prosilver style uses HTML5 and CSS3 and is designed for desktop and mobile browsers. phpBB supports UTF-8 and offers language packs for additional translations. It hashes passwords before storing them; newer platforms use Argon2id and Argon2i hashing. Support resources include documentation, knowledge base articles, community forums, and limited-support Discord and IRC chats. Administrators are instructed to remove the install directory after installation because leaving it can create a security issue. phpBB is released under the GNU General Public License v2.
