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。
