1、当插入大量数据时，ajax和普通post哪个效率更高？
2、当查询大量数据时，ajax、普通get、普通post哪个效率更高？
回复讨论(解决方案)
都一样！
表单内置有 get、post 提交
Ajax 通过 XMLHttpRequest 组件完成 get、post
如果一定要抠字眼，肯定post效率最低，但是这种差异真的能在你的业务逻辑中体现出来的话估计你也不会来这里问这种问题了。所以随意用吧，不过出于对用户体验优化的考虑，建议用ajax做提交和查询
查询大量数据的话，查询条件多了get提交是不行的，需要用post，

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.
