This removes all items with null values recursively on multideminsional arrays. Works on PHP >= 5.6. If you want to remove all "empty" values, replace !is_null($value) with !empty($value).

function recursivelyRemoveItemsWithNullValuesFromArray(array $data = []): array
{
    $data = array_map(function($value) {
        return is_array($value) ? recursivelyRemoveItemsWithNullValuesFromArray($value) : $value;
    }, $data);

    return array_filter($data, function($value) {
        return !is_null($value);
    });
}
