PHP array_key_last function

The PHP function array_key_last retrieves the last key of the array without affecting the pointer’s position within the array.

Description / Descripción
array_key_last(array $array): int|string|null

Parameter

$array – the array from which we will get the last key.

Return

Returns the last key of the array if the array is not empty; otherwise, it will return null.

Example

In this case, we’ll use the same example we saw with array_key_first, but we’ll use array_key_last to find the key of the last element.

$marcasDeAutos = array(
    "Toyota",
    "Ford",
    "Honda",
    "Chevrolet",
    "Volkswagen",
    "BMW",
    "Mercedes-Benz",
    "Audi",
    "Nissan",
    "Hyundai",
    "Kia",
    "Subaru",
    "Mazda",
    "Lexus",
    "Jeep",
);

echo(array_key_last($marcasDeAutos));
