我总觉得挺难的 可以告诉我学习方法吗 ? 谢谢大神们

看看视频教程

学习 php 和学习任何一种计算机语言都是一样的:
计算机很无知,所以你需要细致的描述每一步都怎么做
你先要学会用人类语言准确的描述你要做什么和怎么做
然后把所有的怎么做翻译成计算机语言(比如php)
------解决方案--------------------
培训机构多是填鸭式的 在短时间内提供大量的东西
如果想学的比较好,一定不能下午下课就走了 呆到9点钟把今天学的东西好好咀嚼一下 亲自动手写一写
有人从培训机构出来 还是什么都不会 有人却能真的从0开始入门
加油.
------解决方案--------------------
自己先看看自己有没有兴趣吧,需要可以去网上搜,可以先从基础学习!加油

不错,学习的东西需要时间消化才行。

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.
