Question

How to I get an array of the last n items of another array in PHP?

Answer 1

You can use array_slice:

$arr = array_slice($old_arr, -$n, $n, true);

If the array indices are meaningful to you, remember that array_slice will reset and reorder the numeric array indices. You need the preserve_keys flag (4th parameter) set to true to avoid this.
