Note Submitter: spamt at maro dot net ---- I tried the above quicksort clip and it would send my script into an endless loop every time. A little more investigation into sorting multi-dimentional arrays resulted in finding how to implement the array_multisort function properly to do this. Array_multisort lets you take a multi-dimentional array and sort by one column, keeping all your rows in line. Here's what I did: With a two dimentional array of numbers stored in cat[X][Y], I wanted to sort by the second column of numbers (descending), but have it keep the corresponding number in the first column lined up with it's partner. CAT: 0 1 <- X __Y____________ : 1: 1 3 : 2: 0 6 : 3: 5 2 : 4: 8 4 To result in: CAT: 0 1 <- X __Y____________ : 1: 0 6 : 2: 8 4 : 3: 1 3 : 4: 5 2 array_multisort($cat[1], SORT_NUMERIC, SORT_DESC, $cat[0]);
