Remove elements from array?

how would I remove all array elements but last 5 ones? The array is a log, but the log will become extensive so I just want to see the five recent items (a.k.a. last five elements)

Answer 1

Use array_slice:

$a5 = array_slice($arr, -5);

Answer 2

$new = array_slice($old, -5)
