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。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
