php会话出现问题,怎么搞会回呀？初学者，请各位帮帮忙谢谢？
以前还可以，不过改了这里之后 session.save_path = "D:/session"
就出现这种情况了，还请各位大神帮帮忙，谢谢了！
------解决思路----------------------
在 session 開始之前有錯誤輸出,先檢查一下你的代碼把錯誤排除掉
------解决思路----------------------
请检查下D盘下session目录是否存在。
------解决思路----------------------
D:/session 是否存在，且有權限寫？
------解决思路----------------------
为什么要改session.save_path 的值呢，改回去试试看。
------解决思路----------------------
session.save_path 的默认值为 /tmp，即操作系统的临时文件目录
可以不设置（注释掉 session.save_path）
如果设置了，则必须保证该目录具有一般用户完全控制权限
------解决思路----------------------
好像session_start()前面不能有输出，

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.
