The big advantage of separate functions is that they make the intent clear; we could combine all four functions into one: array_index(int $position, bool $key), but "array_key_last($something)" is a lot clearer to read than "array_index($something, -1, true)". Are there actually use cases for getting "the 5th key from the end of the array", common enough to make "the last key in the array" harder to write? Regards, -- Rowan Collins [IMSoP]
