SplPriorityQueue::rewind — Rewind iterator back to the start (no-op)
This rewinds the iterator to the beginning. This is a no-op for heaps as the iterator is virtual and in fact never moves from the top of the heap.
This function has no parameters.
Эта функция не возвращает значения после выполнения.
