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 */ 程序1：mainforum.php <html> <head> <link rel="STYLESHEET" type="text/css" href="fp_zhangcg.css"> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <meta name="Microsoft Theme" content="none"> <meta name="Microsoft Border" content="none"> <title>论坛</title> </head> <body bgcolor="#C0C0C0" background="backcolor.GIF"> <?
