What is the purpose of using BBcode in a PHP forum?

BBcode is used in a PHP forum to allow users to format their posts with simple tags, such as [b] for bold text or [url] for hyperlinks. This helps users easily style their posts without needing to know HTML. To implement BBcode in a PHP forum, you can use a library like "BBCodeParser" to parse the BBcode tags and convert them into HTML before displaying the content. 

// Example PHP code snippet using BBcodeParser library
require_once('BBCodeParser.php');

$bbcode = new BBCodeParser();
$bbcode->setText($user_input);
$html = $bbcode->parse();
echo $html;
