    相信每一个到过OSO的人都会对OSO的论坛留下极深的印象,这个论坛无论从那一方面来说都是比较出色的。你想不想你的主页也有这么一个漂亮的论坛呢,其实并不太复杂的,下面我们仅从一些基本的部分来实现对OSO论坛的模仿。
    由于我仅仅是使用这个论坛作为我的留言板,所以我的论坛可以算是OSO论坛的简配。1、在我的论坛中只有在用户登录后才能发言,用户的ID是存在一个叫“cookie_user”的cookie变量中的,2、我的论坛没有子论坛,3、我没有统计一个主题的点击数,4、在OSO论坛中每一个主题前面的表示有没有新贴子的图标我也没设计,5、对于OSO论坛所提供的可选择的主题排列方式以及显示时间段我也没考虑,6、没有会员发贴积分的统计,7、没有版主管理论坛的功能,8、没有贴子编辑的功能。我们将在最后提到如何在我的程序基础上扩充这八项功能。
    首先是一个数据库的设计,事实上一个论坛牵涉到两个数据表,我们暂且将其命名为user、guestbook,在user表中存储的是注册用户的信息。其创建语句如下:
create table my_user(
user_id         char(12)  not null,/*用户名*/
user_password    varchar(8)    not null,/*用户密码*/
PRIMARY KEY (user_id)
)
guestbook中储存的是贴子内容。其创建内容如下:
CREATE TABLE guestbook (
   id bigint DEFAULT '0' NOT NULL auto_increment,/*发言id,自增字段*/
   name varchar(12) NOT NULL,/*主题创建人*/
   type tinyint NOT NULL,/*类型0-回复;1-主贴*/
   theme varchar(50) NULL,/*主题*/
   content blob NOT NULL,/*内容*/
   icon tinyint NOT NULL,/*表情图标*/
   time_open datetime not NULL,/*主题创建时间*/
   time_close datetime not NULL,/*最后回复时间*/
   answer_count int not null,/*回复数*/
   answer_name varchar(12) not null,/*最后回复人*/
   main_id bigint null,/*主贴id*/
   PRIMARY KEY (id)/**/
);
程序包含五个php源代码:分别是connect.inc.php,faq.php,read.php,post.php,reply.php,post_end.php
connect.inc.php:(用来连接数据库)

$dbhostname = "localhost";  
$dbusername = "";  
$dbpassword = "";
$dbName = "";  
MYSQL_CONNECT($dbhostname, $dbusername, $dbpassword) OR DIE("Unable to connect to database");
@mysql_select_db( "$dbName") or die( "Unable to select database");  
?>


faq.php:(用来显示主题列表)

  return($ColorStr);
}
