* count(Countable|array $value, int $mode = COUNT_NORMAL): int
* If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count() will recursively count the array.
* This is particularly useful for counting all the elements of a multidimensional array.
*
* Returns the number of elements in value. Prior to PHP 8.0.0, if the parameter was neither an array nor an object that
* implements the Countable interface, 1 would be returned, unless value was null, in which case 0 would be returned.
