点击更新按钮后会自动刷新页面，然后在页面最上方出现“个人资料修改成功”的提示，看源代码就是ajax提交一个post到/api/setting然后根据返回的json判断更新成功，然后使用window.location.reload()刷新页面。

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
