What is a forum? Early Internet forums could be described as a web version of a newsgroup or electronic mailing list (many of which were commonly called Usenet) ; allowing people to post messages and comment on other messages. Later developments emulated the different newsgroups or individual lists, providing more than one forum, dedicated to a particular topic.
Forums perform a function similar to that of dial-up bulletin board systems and Usenet networks that were common from the late 1970s to the 1990s. Early web-based forums date back as far as 1996. A sense of virtual community often develops around forums that have regular users. Technology, computer games and/or video games, sports, music, fashion, religion, and politics are popular areas for forum themes, but there are forums for a huge number of topics. Internet slang and image macros popular across the Internet are abundant and widely used in Internet forums.
Few of the Most popular PHP driven forums are PHPBB, Invision Board and VBulletin. But today I’m not here to talk about those popular packages; I’m here to list out the possible alternative quality PHP forums available around the globe.
