Discuz Forum Optimization: Quickly handle user data cleanup

In the process of running the Discuz forum, as the number of users increases, the user data will become larger and larger, which requires regular data cleaning to optimize the performance of the forum and users. experience. This article will introduce how to quickly handle user data cleanup through some specific code examples and improve the operating efficiency of the Discuz forum.

First of all, we need to pay attention to some common user data cleaning issues, such as cleaning invalid users, cleaning expired data, etc. To address these problems, we can automate processing by writing some scheduled tasks. Here are some code examples:

1. Clean up invalid users:

   <?php
   require_once './source/class/class_core.php';
   $discuz = C::app();
   $discuz->init_cron = false; // 关闭Discuz 的计划任务
   
   // 获取需要清理的无效用户列表（根据自定义的条件来筛选）
   $invalidUsers = C::t('common_member')->fetch_all_invalid_users();
   
   if ($invalidUsers) {
       foreach ($invalidUsers as $uid) {
           // 删除无效用户的相关数据
           C::t('common_member')->delete_invalid_user($uid);
           C::t('forum_thread')->delete_invalid_user_threads($uid);
           C::t('forum_post')->delete_invalid_user_posts($uid);
           // 其他需要清理的数据，根据实际情况自行添加
       }
   }

2. Cleaning expired data:

   <?php
   require_once './source/class/class_core.php';
   $discuz = C::app();
   $discuz->init_cron = false; // 关闭Discuz 的计划任务
   
   // 获取需要清理的过期数据列表（根据自定义的条件来筛选）
   $expiredData = C::t('forum_thread')->fetch_expired_threads();
   
   if ($expiredData) {
       foreach ($expiredData as $tid) {
           // 删除过期数据
           C::t('forum_thread')->delete_expired_thread($tid);
           // 其他需要清理的数据，根据实际情况自行添加
       }
   }

The above code examples are for reference only. The actual data cleaning needs to be adjusted according to the situation of the specific forum to ensure the accuracy and completeness of the data. At the same time, in order to avoid irreversible losses caused by misoperation, it is recommended to back up relevant data before performing data cleaning.

Through the above code examples, we can quickly clean up user data, optimize the performance of the Discuz forum, and improve the user experience. I hope this content will be helpful to webmasters who are facing similar problems.
