This class is based on jquery’s markitup plugin function, i did some code compressions and added youtube handler to it. If you need base_defines function, just search the site.

class BBCodeParser {
	private $text;

	public function __construct() {
		base_defines(array(
			"EMOTICONS_DIR" => "/img/emoticons/"
		));
	}

	public function escape($s) {
		$this->text = strip_tags($this->text);
		$code = $s[1];
		$code = htmlspecialchars($code);
		$code = str_replace("[", "[", $code);
		$code = str_replace("]", "]", $code);
		return '<pre><code>'.$code.'</code></pre>';
	}	

	public function removeBr($s) {
		return str_replace("<br />", "", $s[0]);
	}

	public function parse($text) {
		$this->text = trim($text);
		$this->text = preg_replace(array(
				'/\[b\](.*?)\[\/b\]/ms',
				'/\[i\](.*?)\[\/i\]/ms',
				'/\[u\](.*?)\[\/u\]/ms',

		$this->text = nl2br($this->text);

		// clean some tags to remain strict
		// not very elegant, but it works. No time to do better ;)
