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/>";
