PHP数组函数实现栈与队列的方法介绍（代码示例）

根据php提供的四个关于数组的函数：

array_push(),array_pop(),array_unshift(),array_shift()

配合数组本身,一下子就实现了栈(stack)和队例(quene),

<?php
$rangelist = array("淘宝", "天猫", " VIP");
//入栈
array_push($rangelist, "拼多多");
array_push($rangelist, "JD");
var_dump($rangelist);
echo "<br/>";//array(5) { [0]=> string(6) "淘宝" [1]=> string(6) "天猫" [2]=> string(4) " VIP" [3]=> string(9) "拼多多" [4]=> string(2) "JD" }
//出栈
$result = array_pop($rangelist);//JD
var_dump($result);
echo "<br/>";
$result = array_pop($rangelist);//拼多多
var_dump($result);
echo "<br/>";


$quenelist = array("三星", "LG", "惠而浦");
//入队
array_unshift($quenelist, "海信");
array_unshift($quenelist, "科龙");
var_dump($quenelist);
echo "<br/>";//array(5) { [0]=> string(6) "科龙" [1]=> string(6) "海信" [2]=> string(6) "三星" [3]=> string(2) "LG" [4]=> string(9) "惠而浦" }
//出队
$res = array_shift($quenelist);//科龙
var_dump($res);
echo "<br/>";
$res = array_shift($quenelist);//海信
var_dump($res);
echo "<br/>";
