The SplQueue class

(PHP 5 >= 5.3.0, PHP 7)

简介

SplQueue 类通过使用一个双向链表来提供队列的主要功能。

SplQueue extends SplDoublyLinkedList implements Iterator , ArrayAccess , Countable {

/* 方法 */

setIteratorMode ( int $mode ) : void

SplQueue::__construct — Constructs a new queue implemented using a doubly linked list
SplQueue::dequeue — Dequeues a node from the queue
SplQueue::enqueue — Adds an element to the queue
SplQueue::setIteratorMode — Sets the mode of iteration
