一直想弄个discuz的数据采集程序，这2天研究了下discuz发帖涉及的几个数据库表，这里分享一下自己的处理方法。
discuz发表主题设计的几个表：（这里列出了主要的几个相关的表）
1、主题表 pre_forum_thread：这个表一个主要数据就是 tid 主题ID
2、post 分表协调表 pre_forum_post_tableid：这里需要获取一个自增的 pid
3、帖子表 pre_forum_post ：记录主题pid、fid、tid、title、content等主要信息
4、版块表 pre_forum_forum：这里主要更新版块的主题、帖子数量
5、帖子主题审核数据表 pre_forum_thread_moderate：这个可以根据自己状况决定，并不是必须的
6、用户统计表 pre_common_member_count：主要是更新用户的主题数量
大致流程是这样的：
第一步：向 主题表 pre_forum_thread 中插入版块ID、用户ID、用户名、帖子标题、发帖时间等信息。
第二步：获取第一步插入表 pre_forum_thread 的数据ID，作为主题ID,即 tid
第三步：向 post 分表协调表 pre_forum_post_tableid 插入一条数据，这张表中只有一个自增字段 pid
第四步：获取 第三步 插入表 pre_forum_post_tableid 的数据ID，作为 pid 第五部：向帖子表 pre_forum_post 中插入帖子相关信息，这里需要注意的是： pid为第四部的pid值，tid为第二步的tid值
第六部：更新版块 pre_forum_forum 相关主题、帖子数量信息
第七步：更新用户 pre_common_member_count 帖子数量信息
discuz发帖过程主要就是以上7个步骤，通过这几个步骤就可以完成对实现discuz的发帖流程，其中设计到一些积分等其他信息的可以自己加上。 <?php
