类似QQ空间的评论表是怎么设计的。
如果是存在一张表里，能只使用一条语句就可以查询处理的吗？难道只能分两次查询？

一条可以，php处理无限分类就是了。
一次就OK，结构自己组装

带有分页功能。。。 暂时能想到的就是一次读取所有，程序自己分页。为防止出现错乱，每页最后的ID作为参数传出，请求下一页时作为分页依据

每分一次页，全部取出来会不会太坑了。。

要么取出来的时候麻烦，要么存进去的时候更麻烦，选一样。主要是这种评论本来就不是绝对顺序的。对于QQ这种评论来说很难有超长的评论，一次全取没有问题

是每一页都一次取，而且QQ还可以支持二级里收起展开评论

我的意思是每次请求都把数据全读出来分页，每次点下一页都要请求一次读一次数据库。至于收起展开二级评论只是前端的小把戏
现在的网速都很快，ajax 技术也很成熟。没有必要再去纠结了
首次读取主贴一页，回复按需用 ajax 加载。简洁明了，算法简单
基于这中架构，只需按邻接列表组织数据即可

版大的意思采用两次去读取吗，第一次先读取一级评论，第二次再去读取二级评论也就是回复的意思吗？
是的，第一次先读取一级评论，第二次再去读取一级评论的二级评论
即开始是全部折叠的，点击才展开

那不就是在一级评论集下面foreach循环再去读取，这样会不会太慢了。。。我默认是会显示出两条二级评论。

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
