php线性表的入栈与出栈实例分析

本文实例讲述了php线性表的入栈与出栈用法。分享给大家供大家参考。具体如下：

    <?php 
    $stack = array("Simon", "Elaine"); //定义数组 
    array_push($stack, "Helen", "Peter"); //入栈 
    print_r($stack); 
    ?>

    <?php 
    $stack = array("Simon", "Elaine"); //定义数组 
    array_unshift ($stack, "Helen", "Peter"); //入栈 
    print_r($stack); 
    ?>

    <?php 
    $stack = array("Simon", "Elaine", "Helen", "Peter"); 
    echo array_pop($stack)."/n"; //出栈 
    print_r($stack); 
    ?>

    <?php 
    $stack = array("Simon", "Elaine", "Helen", "Peter"); 
    echo array_shift($stack)."/n"; //出栈 
    print_r($stack); 
    ?>

希望本文所述对大家的php程序设计有所帮助。
