PHP - “神奇变量值” - 酷还是傻瓜？ [关闭]

Question

I have some questions about designing a code framework using Dependency Injection:

FLOW3 or Doctrine uses Annotations to inject class instances to object properties. This is done with Code Reflection... and the performance is baaaaad :D

What do you think about this approach?

class Test extends Injector {
    protected $abc = '@Inject:/namespace/classname';
}

The Injector just loop through the class properties and finds if the string begins with @Inject and create object of given class.

Is it cool or does it suck?

Answer 1

If you're not using a cache with Doctrine's annotations (which are more elegant than your solution, which would be insanely difficult to debug [which is actually the only problem with it other than in the case that you need a string with '@Inject' in it] if something went wrong), then you're doin' it wrong. In a production environment, if you set up caching properly (see the docs) you won't have any issues :)
