现在做个网站其实成本很低,asp空间,淘宝上才10元一年。100M的。php也差不多是10元一年。
?
域名.cn的才20元一年。。。算下来。一个网站一年才30元的成本。。。
?
随便做个网站。放个google广告。就能成本赚回来。。。
?
如果做一百个网站。你就可以在家睡觉收钱啦。哈哈
?
不过google被国封了。真心不好做。
?
真正做起来很难了。这就是所谓的网站群。

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.
