为什么静态方法不能操作静态变量?
为什么静态方法不能操作静态变量?解释下哈。。
------解决方案--------------------
静态方法在编译期间就已定义，而操作非静态变量需要一个对象。而这个对象是在运行时才产生的。
大概来说，非静态方法可以操作静态方法和变量。而静态方法不能操作非静态方法和变量。（不过，实际上 php中可以违规的静态调用非静态方法）

我说错了没什么关系，只要你不由此变傻就可以了

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.
