基于PHP+mysql实现新闻发布系统的开发

-- 数据库: `newsdb`
CREATE DATABASE IF NOT EXISTS `newsdb` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
USE `newsdb`;
-- 表的结构 `news`
CREATE TABLE IF NOT EXISTS `news` (
 `id` int(9) NOT NULL AUTO_INCREMENT,
 `title` varchar(50) NOT NULL,
 `keywords` varchar(50) NOT NULL,
 `author` varchar(16) NOT NULL,
 `addtime` datetime NOT NULL,
 `content` text NOT NULL,
 PRIMARY KEY (`id`)
  ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;
