内存满了的情况下，Session存储是怎么办
内存满了的情况下，Session存储是怎么办，如标题~
------解决思路----------------------
session 默认情况下是存储在硬盘上的以sessionid命名的文件。

具体可参见php.ini中
session.save_handler

默认值是 files 文件存储。

如果是使用memcache或者其他缓存方式在内存中存储，在内存空间不足的情况下会存储失败，也就是内存溢出的情况。
此时需要设置报警或者检测机制，在存储前检测内存空间使用情况，如果不足就需要对就数据进行清理。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You 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.

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.
