I know nothing about php but what is wrong with this bit of code

* Add a 2-D array of messages by lang. Useful for extensions.
	 *
	 * @param array $messages The array to be added
	 */
	function addMessagesByLang( $messages ) {
		wfProfileIn( __METHOD__ );
		foreach ( $messages as $key => $value ) {
			$this->addMessages( $value, $key );
		}
		wfProfileOut( __METHOD__ );
	}

You are missing a / before the first asterisk, so the comment is being treated as code to be excecuted

 

Also, when posting to a forum, you'll want to use the

 tag.  Just put it around your code, so it looks like this:

[code]* Add a 2-D array of messages by lang. Useful for extensions.
*
* @param array $messages The array to be added
*/
function addMessagesByLang( $messages ) {
wfProfileIn( __METHOD__ );
foreach ( $messages as $key => $value ) {
$this->addMessages( $value, $key );
}
wfProfileOut( __METHOD__ );
}
