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
