If you want to calculate the sum in multi-dimensional arrays:

function array_multisum(array $arr): float {
    $sum = array_sum($arr);
    foreach($arr as $child) {
        $sum += is_array($child) ? array_multisum($child) : 0;
    }
    return $sum;
}
?>

Example:

$data =
[
    'a' => 5,
    'b' =>
    [
        'c' => 7,
        'd' => 3
    ],
    'e' => 4,
    'f' =>
    [
        'g' => 6,
        'h' =>
        [
            'i' => 1,
            'j' => 2
        ]
    ]
];
