你搭建一个php环境，实在不会可以下载一个wamp集成安装，然后把这个项目全部放在一个文件夹里，之后放在wamp安装目录下一个www的文件夹里。之后通过浏览器，输入：localhost，点击你新建的那个文件夹就可以
数据库的创建
CREATE DATABASE GBOOK;
CREATE TABLE `gbook` (
`id` INT( 255 ) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 10 ) NOT NULL ,
`sex` TINYINT( 1 ) UNSIGNED NOT NULL ,
`email` VARCHAR( 255 ) NOT NULL ,
`info` TEXT NOT NULL ,
`ip` VARCHAR( 15 ) NOT NULL ,
`time_at` DATETIME NOT NULL
)
主要页面有:
input.html为初始页
insert.php为把输入内容送入数据库
show.php显示留言板内容
change.php修改留言板内容的界面
del.php删除留言板内容
change_ok.php修改留言板内容并送入数据库
