Wikia is a MediaWiki markup parser based on "Mediawiki2HTML machine",but a lot of new markup and map generator added and some patterns fixed.
Wikia convert MediaWiki markup to html and is easy to use: Just include wikia.inc.php and call parse function. In addition you can generate map of content headers by calling generateMap function.
require_once("wikia.inc.php");
$content=htmlspecialchars($content);
echo generateMap($content);
echo parse($content);
