If you can have:
$array = array(array('1','2','3'),array('2','3','1'));
You can use this:
$key = array_search($search_for,$array[0]);
if($key !== FALSE)
{ $array[1][$key] += $add_value; }
Otherwise, with the way you have your array now, you have to search
$array[0][0], $array[1][0], $array[2][0], etc, with a loop.
