array with two dimensions

Hi all, Got a little problem here, I have a mysql query that looks like this SELECT SUM(value) as value, YEAR(dileveret) as year FROM table GROUP BY YEAR(dileveret) It works just fine, but i need to make a array that can could do somthing like this (know it doesent work) $ALL_VALUES[$year] += $value; The script is running the script up to 100 times to get all the specific data's, i hope that you know a way that i can hold the values, and year and later print one value for each year.. THANKS A LOT! Regards Lasse (newbie)
