预定义常量
MultipleIterator::MIT_NEED_ANY- Do not require all sub iterators to be valid in iteration.
MultipleIterator::MIT_NEED_ALL- Require all sub iterators to be valid in iteration.
MultipleIterator::MIT_KEYS_NUMERIC- Keys are created from the sub iterators position.
MultipleIterator::MIT_KEYS_ASSOC- Keys are created from sub iterators associated information.
