	/**
	 * Post-parser
	 *
	 * Use this method in case you want to alter the parsed bbcode.
	 * The newline placeholders are still available and any remaining will be removed in the last step before output
	 *
	 * Example: you want the "img" bbcode to use database images instead of user URLs.
	 * You'd go and change the tag so that it only accepts digits like [img=123456]
	 * and replace any occurence with a unique placeholder like {__IMG#ID__}.
	 * Now the post-parser gets into play: you preg_match_all() out all your placeholders,
	 * grab the images in a single query from the database and replace them with their respective <img> tag
	 * or whatever replacement and any corrupt id with a placeholder image. Profit!
	 *
	 * @param string $bbcode bbcode
	 *
	 * @return string postparsed bbcode
