$GLOBALS['dummy2'] = preg_replace('~([Ww]heat|[Tt]hins)~e', "strtolower('$1')", $GLOBALS['dummy']);

The second test, "preg_replace_callback()", was:

/*
function cb($match)
{
	return strtolower($match[0]);
}
*/

$GLOBALS['dummy2'] = preg_replace_callback('~([Ww]heat|[Tt]hins)~', 'cb', $GLOBALS['dummy']);
