一个模仿oso的php论坛程序(之一)_php实例

我经常使用oso的论坛,个人感觉挺好的,因此模仿oso的界面编了一个程序,与大家共享。
程序由三部分组成,即显示主题信息,显示论坛信息,增加论坛信息,主题与论坛内容采用主从表关系。
表结构如下:
drop table fr_t_forumtitle;
create table fr_t_forumtitle(  
   id         integer,  
   state      varchar(1),  
   readcount  integer,  
   replycount integer,  
   title      varchar(100),  
   createman  varchar(20),  
   replyman   varchar(20),  
   replytime  datetime);

drop table fr_t_forumcontent;

create table fr_t_forumcontent(  
   id          integer,  
   replyman    varchar(20),  
   replytime   datetime,  
   replyemail  varchar(100),  
   replyhttp   varchar(100),  
   replyface   smallint,  
   content     text);

drop table fr_t_parameter;

create table fr_t_parameter(  
   code    varchar(10),  
   name    varchar(40),  
   content varchar(10));  
insert into  fr_t_parameter(code,name,content) values('pageline','分页数','20'); /* 调整该参数可以修改每页行数 */
