PHP session实现购物车功能

php  /  管理员 发布于 7年前   261

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

<?phpheader("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
