Examples

1 · array size

<?

$array = array('a', 'b', 'c', 'd', 'e', 'f');
$size = 2;

$return = array_chunk($array, $size);

print_r($return);

?>
Array
(
    [0] => Array
        (
            [0] => a
            [1] => b
        )

    [1] => Array
        (
            [0] => c
            [1] => d
        )

    [2] => Array
        (
            [0] => e
            [1] => f
        )

)

2 · preserve_keys

<?

$array = array('a', 'b', 'c', 'd', 'e', 'f');
$size = 2;
$preserve_keys = true;

$return = array_chunk($array, $size, $preserve_keys);

print_r($return);

?>

    [0] => Array
        (
            [0] => a

        )

    [1] => Array
        (
            [2] => c
            [3] => d
        )

    [2] => Array
        (

            [5] => f
        )
