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：
