PHP get the last 3 elements of an array

Question

I have an array:

[13] => Array
        (
            [0] => joe
            [1] => 0

    [14] => Array
        (
            [0] => bob
             


        

Answer 1

You can use array_slice():

<?php
    // -3 = start from the end
    // true = preserve_keys
    $result = array_slice($array, 0, -3, true); 
?>

Answer 2

Use array_slice:

$res = array_slice($array, -3, 3, true);

Answer 3

If you want to preserve key, you can pass in true as the fourth argument:

array_slice($a, -3, 3, true);

Answer 4

You can use array_slice with offset as -3 so you don't have to worry about the array length also by setting preserve_keys parameter to TRUE.

$arr = array_slice($arr,-3,3,true);
