}示例2: SplDoublyLinkedList
* 栈SplStack
* 队列SplQueue
*
* 栈和队列都是继承于双向链表，所以，所有双向链表的方法都可以被栈和队列使用。调用方法也一致。
*/

// 在结尾插入一个新值

// pop()
// 抛出结尾的一个元素，会使得链表结构减少一个
$list->pop();
// key()
// 获得当前节点的索引值
$list->key();
// count()
// 获得链表的数量
$list->count();
// rewind()
// 将指针返回至初始节点
$list->rewind();
// current()
// 获得当前节点
$list->current();
// top()
// 返回最后一个节点的值

/**

* original iterable will be preserved.
*
* This iterable will be consumed in its entirety when `reverse()` is called.

* // => [4 => 'e', 3 => 'd, 2 => 'c', 1 => 'b', 0 => 'a']
