PHP session实现购物车功能

在wamp环境下,用PHP的session会话控制完成购物车的效果,数据存放在数组里练习,没有连接数据库,效果不错,简单易懂,以下是各部分的代码

common.php

<?php

header("content-type:text/html;charset=utf-8");

$arrPro = array(

array('id'=>1,'img'=>'img/1.jpg','title'=>'小米移动电源5000mAh','price'=>49),

array('id'=>2,'img'=>'img/2.jpg','title'=>'20000mAh小米移动电源2','price'=>149),

array('id'=>3,'img'=>'img/3.jpg','title'=>'小米圈铁耳机Pro','price'=>129),

array('id'=>4,'img'=>'img/4.jpg','title'=>'小米家电动滑板车','price'=>1999),

array('id'=>5,'img'=>'img/5.jpg','title'=>'小米笔记本','price'=>3499),

array('id'=>6,'img'=>'img/6.jpg','title'=>'米家LED智能台灯','price'=>169),

array('id'=>7,'img'=>'img/7.jpg','title'=>'小米体重秤','price'=>99),

array('id'=>8,'img'=>'img/8.png','title'=>'小米电视3s 48英寸','price'=>2599)

);

index.php

<?php

session_start();

$sum = 0;

$class = "";

//判断左上角购物车的样式显示

if(!empty($_SESSION['shopcar'])){

$data = $_SESSION['shopcar'];

$sum = array_sum($data[4]);

$class = "on";

//右上角圆点

if(empty($data[0])){

$class = "";

}

}
