Re: Sort a multi-dimensional array on a certain key followed by another key

TS wrote:

Ok so, I have an array [0(index)][1st key][2nd key] Basically I don't care about the index. As a matter of fact I'd prefer it reset to still be in order afterwards. However, I need to sort the 1st key and keep correlation w the second key. Then sort on the second key. I have video volumes and scenes like [0][110][1] [1][110][3] [2][110][2] [3][110][4] Any help would be much appreciated.
