BBCode is an abbreviation for Bulletin Board Code, the lightweight markup language used to format posts in many message boards. It is also called forum codes. The available tags are usually indicated by rectangular brackets surrounding a keyword, and they are parsed by the message board system before being translated into a markup language that web browsers understand, usually HTML or XHTML.<?php
