PHP基础示例：商品信息管理系统v1.1

实现目标：使用php和mysql写一个商品信息管理系统，并带有购物车功能

一、创建数据库和表

　　1.创建数据库和表：demodb

　　2.创建表格：goods

　　字段：商品编号，商品名称，商品类型，商品图片，单价，商品描述，库存量，添加时间

二、创建php文件编写代码(以下为要创建的php文件及其用途)

　　add.php　　商品添加页面

　　edit.php 商品信息编辑表单页

　　index.php　　商品信息浏览页

　　action.php　　执行商品信息添加和修改及删除等操作处理

　　dbconfig.php 公共配置文件，数据库连接配置信息

　　menu.php　　网站公共导航栏

　　uploads/ 　　上传图片的存放目录

　　function.php 公共函数库文件：图片信息的上传，等比缩放等处理函数

　　addCart.php 添加购物车信息的操作（向SESSION放入要购买的信息）

　　myCart.php 实现了购物车信息的浏览操作，并且实现商品信息的统计（小计和总价）

　　clearCart.php 实现了购物车信息的单个商品删除或清空购物车操作

　　updateCart.php 修改购物车中商品的数量，防止过小约束

各php文件关系图示：

好，那下面是代码部分：

首先是建表语句：

以下为各php文件代码，需要的朋友可直接将各代码复制并放到同一目录下即可，还要在同目录下创建uplaods文件夹存放上传图片
