ThinkPHP infinite classification principle to implement message and reply function examples, thinkphp examples

The message board program described in this article uses the principle of unlimited classification, which can realize unlimited messages and replies. The message list gclist retains message hierarchical spaces to make messages and replies clearly hierarchical. Share it with everyone for your reference. The specific analysis is as follows:

Functionally, this program can achieve unlimited levels of messages and replies, that is, reply to messages and reply to messages in reply. Of course, you can also make limited control so that it can only reply to messages. The key is to remove "reply to this message" in the reply message in the template code. Welcome to Paizhuan!

The program effect is as shown below:

php留言板是实现无限回复功可以

个人觉得建立一个专门的数据库表就可以了，给每个回复一个id然后在每次有回复后将这个id对应的回复写入表中就ok了！
回复内容表：
回复Id 回复内容

回复关联表：
回复内容id 回复内容id

这样就可以实现无限回复了！
