(PHP 5 >= 5.3.0)

简介

The SplStack class provides the main functionalities of a stack implemented using a doubly linked list.

the SplStack is simply a SplDoublyLinkedList with an iteration mode IT_MODE_LIFO and IT_MODE_KEEP

<?php # Think of the stack as an array reversed, where the last element has index zero $stack = new SplStack(); $stack->push('a'); $stack->push('b'); $stack->push('c'); $stack->offsetSet(0, 'C'); # the last element has index zero $stack->rewind(); while( $stack->valid() ) { echo $stack->current(), PHP_EOL; $stack->next(); } ?>
