Well, I can't really help here without seeing some relevant code. You may be right,
and what you are doing does require no gaps in your keys -- but it may be that you can
program round that more efficently than you can re-index the array when you delete a
value.
That said, I'd answer your original question with:
array_splice($arr, $n, 1);
which should actually be pretty efficient!
Cheers!
