phpBB is a popular free and open source forum system written in the PHP programming language; the name "phpBB" is an abbreviation of "PHP Bulletin Board".

History

phpBB was started by James Atkinson as a simple UBB-like forum for his own website on June 17, 2000. Nathan Codding and John Abela (both now former team members) joined the development team after phpBB went into SourceForge CVS, and work on 1.0.0 began. A fully-functional, pre-release version of phpBB was [ready] by July 1, 2000.

phpBB 1.0.0 was released on December 9, 2000, with subsequent improvements to the 1.x codebase coming in two more major installments. The final release in the 1.x line was phpBB 1.4.4, released on November 6, 2001. During the lifetime of the 1.x series, Bart van Bragt, Paul S. Owen (former co-manager of the project), Johnathan Haase (now a former team member) and Frank Feingold joined the team.

phpBB 2.0.x was begun on February 17, 2001. It was developed entirely from scratch; the developer's ambitions for phpBB had outgrown the original codebase. Doug Kelly (now a former team member) joined the team shortly afterwards. After a year of development and extensive testing, phpBB 2.0.0, dubbed the "Super Furry" version, was released on April 4, 2002 (three days later than intended). [phpBB forum post] covering history from 2000–2002

In December 2004, a large number of Web sites were defaced by the Santy worm, which used vulnerabilities in outdated versions of phpBB to overwrite PHP and HTML pages.

The latest release in the 2.0.x line is [2.0.21] ("Bertie's Summer Vacation"), on June 7, 2006, and the latest in the 3.x line is [3.0 Beta 1] on June 17, 2006. Releases in the 2.0.x line are restricted to bug and security fixes only.

Future versions

With the new 2.0.x codebase in a stable state, the development team, now led by Meik Sievertsen, has begun building upon and altering the codebase to produce "Olympus"; when it reaches production quality, it will be released as 3.0.0. The improvements in "Olympus" to date are comparable with the improvements between 1.4.x and 2.0.x. It was originally planned to be released as 2.2.0; however, since 2.1.x eliminated virtually all compatibility with the 2.0.x line, the version number for release was changed to 3.0.0, in keeping with the Linux kernel version numbering scheme. [phpBB 2.2 is no more ... meet Olympus] from the phpBB community forums

A list of new features [Olympus Feature Highlights] that will be included in version 3.0.0 can be found at [area51] (development site of phpBB.com). Also, a summary of many features implemented as of May 2003 exists [A summary] of phpBB 3.0 (development) features included by May 2003, with another more concise summary [A concise summary] of phpBB 3.0 (development) features included in April 2003 dating from April of 2003. It is possible that not all of these features will make it to the final version, and that others will be added. The addition of new developers to the phpBB team has increased [phpBB] CVS statistics the pace of development from a long lull.

On March 19, 2006, the development team opened a public bug tracker for the CVS version, and on June 17, 2006 the first beta version of 3.0 was released. [Beta 1 announcement]

Technology

Multiple database systems are supported via an abstraction layer. These are: MySQL, PostgreSQL, MSSQL, Microsoft Access and, with modification [HOWTO: phpBB with Oracle], Oracle. The phpBB database abstraction layer primarily handles API differences; peculiarities in SQL syntax are dealt with by the application on a per-query basis. phpBB 3.0 sees the addition of SQLite, Firebird, and Oracle.

Abstraction is also applied to the way phpBB presents data to users. Layout is separated from the application code, and defined with templates. Templates, which contain markup as well as variables and blocks, are compiled by phpBB into PHP code and executed. This can be an intensive process; phpBB is distributed with an optional system to cache the compiled templates. Templates typically do not contain text from a specific language. Localised text is contained in language "packs", which contain lists of strings to be substituted into templates as variables. These strings often contain format specifiers, enabling the order of application-supplied variables within each piece of text to be customised.

Recent versions of phpBB 2.0 require PHP version 4.0.3 or above. When initially released, phpBB 2.0 included support for both PHP 3 and PHP 4; subsequent releases have dropped PHP 3 support in favour of easier maintenance. Support is not given http://www.phpbb.com/phpBB/viewtopic.php?t=211009 phpBB statement regarding PHP5 for the use of phpBB2 in conjunction with PHP 5, although the phpBB developers have altered the code to function more properly in such environments. phpBB 3.0 requires PHP version 4.3.3 or above, and is compatible with PHP 5. Although it is not supported, code is also present to allow phpBB3 to run under PHP 6.0.0-dev.

MODs

MOD, in the context of phpBB, is an abbreviation referring to code modifications created by the phpBB community. The term is capitalised to distinguish modifications from forum moderators. Modifications referred to in this manner are not authored by the phpBB developers, and do not enjoy the same level of support as unmodified official code. The phpBB MOD Team accepts modifications from community sources for validation, and modifications which meet the [MOD Team's standards] are made available for download from the phpBB [MOD Database]. Other sites also provide modifications, both validated to their own standards and unvalidated, however the phpBB teams do not offer support for boards using MODs downloaded from sites other than phpBB.com.

Security

The security of phpBB has been disputed, with a series of new versions in a relatively small timeframe addressing security issues. However the phpBB Team usually responds to security reports as soon as possible, and releases a new version quickly. The phpBB Group has also learned from a series of security issues, and phpBB 2.0.18 followed a codebase security audit. Additionally, many things have been changed to avoid problems in the future. Among those are a reauthentification system for the administration panel (this was introduced after a cookie verification issue allowed attackers to gain administrator access), a visual confirmation system (CAPTCHA) to prevent bots from registering, as well as the substitution of the highlighting code, which was the cause for critical vulnerabilities in phpBB 2.0.10 and 2.0.15. In order to keep boards as secure as possible, administrators are urged to keep their board updated to the latest version as soon as possible.

On November 23, 2005, the phpBB Group announced a new Incident Investigation Team, a sub-team of their Support Team, which is responsible for assisting users in the cleanup and repair of an attacked phpBB installation and investigating reports of new exploits. [Announcing the Incident Investigation Team] from the phpBB.com community forums The team announced [a tracker] the following January where administrators of attacked bulletin boards could report an attack and receive support from the IIT.
