php多表联查??
我有2个表
A表: B表:
id title id content
1 a1 a1 内容1
2 a2 a2 内容2
3 a3 a3 内容3
现在我需要根据A表里的title显示3条B表里的content, 也就是大家常说的把分类和内容分表放, 但是取得时候怎么根据A表里的title取得B表的内容。
我要显示3条A表title 但是还要对应B表的content, 分表从来没了解过, 这次大家就来教育教育我吧

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.
