也不知道问题出在那儿

我把session 存在数据库里的，登陆成功后，看数据表里，有一条记录。也有值，，当我刷新页面后，在看数据表里，

看到 session值清空了，并且插入了很多没有数据的记录。那些记录只有sessionid 没有值。

然而

我在本地测式的时候，就只有一条记录 sessionid 和值不管怎么刷新都只有这一条。

程序都一样啊怎么会这样呢、

服务器 os + nginx
本地 windows+apache

php版本一样的。

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select 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.
