and Small Way of program red chat use stage

 
    前阶段,看到mdjwq@yeah.net和稻香居的红蜻蜓的极小版的聊天程序,仔细阅读了他们的代码,感到这是一篇不可多得的代码,特别是对刚入门者,程序里用到了一些技巧,极有参考价值。本人根据他们的代码,结合自己的体会,增加了一些功能(在线人员的管理等),实现方法也从TXT改为MySQL(和PHP搭配之最佳组合),所有程序在本地全部调试通过,希望拥有自己聊天程序的网友可以直接使用。等本人的个人主页全部完成之后,将与论坛结合使用(论坛已经全部安装完成,其他内容也将完成从chinaren到oso迁移),开辟一个Oracle(大型网站数据库平台)与MySQL(和PHP搭配之最佳组合)数据库管理员的信息讨论栏。
论坛信息表:
create table lt_t_online  /* 记录在线人员信息 */
(  /* 名称,最后发言时间,IP地址,状态(0在线 1脱机)  */
    lt_username  varchar(12)               not null,  
    lt_lasttime  datetime                  not null,
    lt_addrip    varchar(20)                   null,
    lt_state     char(1)                   not null     
);

create table lt_t_content  /* 聊天信息表  */
(  /* 发言人,对象,密级,表情,颜色,内容,时间  */
    lt_speaker      varchar(12)               not null,
    lt_speaked      varchar(12)               not null,
    lt_secrecy      char(1)                   not null,     
    lt_face         smallint                      null,
    lt_color        varchar(6)                    null,
    lt_content      varchar(200)              not null,
    lt_time         datetime                  not null
);
