php教程购物车实现代码

关于购物车，这个是在电子商务方面使用的比较多，用户选择好自己的商品需要保存起来，最后去收银台，这很像我们实际生活的超市，所以我现来写一个简单的php购物车实例代码，比较详细只要一步步，处理好就ok了。

些购物车会用到php文件
main.php 显示商品
additem.php把商品加入购物车
cearcart.php删除购物车中的商品
shoppingcart.php 操作类

用户的数据库教程有

inventory
create table inventory (
product tinytext not null,
quantity tinytext not null,
id int(4) default '0' not null auto_increment,
description tinytext not null,
price float(10,2) default '0.00' not null,
category char(1) default '' not null,
key id (id),
primary key (id),
key price (price)
);
insert into inventory values ('硬盘','5','1','80g','5600','1');
insert into inventory values ('cpu','12','2','p4-2.4g','6600','1');
insert into inventory values ('dvd-rom','7','3','12x','2000','1');
insert into inventory values ('主板www.bkjia.com','3','4','asus','5000','2');
insert into inventory values ('显示卡','6','5','64m','4500','1');
insert into inventory values ('刻录机','4','6','52w','3000','1');
