This is not hard to add. For packed arrays this can be done in O(1) time, for non-packed arrays in O(n) worst case. If added, it's best to add the pair array_nth() & array_nth_key() together IMO. However, it's not something I ever really needed nor something that I have seen a demand for. I think this could be left for the future for follow-up work. Kind regards Niels
