I got a question for you as well as for the rest of the community :) Do you really needed? Is is something that you can't finish your project without?
I'm not saying AOP is bad, the main scope is quite nice on paper, academically, but also OLD! Some references for AOP date back to 1994-5. I have to admit, until hearing about it from Victor, I didn't had a clue about it, now I just know what it is but I won't use it. Why? Simple. I don't want more layers of abstractions between my original code and the server. I want to keep it as simple and clean as possible even if it means that I won't be able to write comments that are shorter that the plain old code. Plus, as far as I can tell, I could just as well be using events for my needs instead of comments, or maybe I just didn't got the full view of it. What would that be good for, writing events instead of comments?!? Maybe I just want to have better traceability for the code. Maybe it's better to know that if I write a piece a code, the other people that will come after me when I'm not there, will be able to see __CODE__ not comments or code hidden somewhere else. I want to be able to see what's going to be executed as much as possible. Ok, so there'll be a AOP extension. GREAT! Now convince the sys-admins to install it. More over you know what they'll ask? Is this safe? Does it crash under load? does it block something? Can it have memory leaks? Is it threadsafe? Can't you program without it? And if you've never heard those questions about __ANY__ third party or even PHP extension then either your sys-admins don't care, don't know, do extensive tests and know what you need it for/how it works better that you or you simply didn't worked into a enterprise environment. So we have this already, Doctrine is using annotations, Symfony2 is doing it and so on but the question stands: Do we __REALLY__ need? In the framework? When everyone on the industry wants faster frameworks, easier to use features from the frameworks, a better/faster PHP engine and so on? Is it stopping Symfony2 from being waay faster that Zend Framework2? Is it stopping Symfony2 to be clean and relatively easy to pick up by new people? I know, once you've found a new toy you'll see it used everywhere but you always have to ask yourself: do I really need it here? Is PHP suited for AOP? Do I need a way to change the classes at runtime? Do I need a way to hide the implementation from the programmer who'll then spend hours trying to debug something that he doesn't understand? And maybe the most relevant case, can you explain me __WHY__ do you need it in the framework? And if you are going to say: enforce SRP then please don't. Just because you write it somewhere else then compile it at runtime/cache time and write a comment for it it doesn't mean you got your responsibilities separated, it means that you just managed to perform the illusion of separating the concern to the end user while introducing him to whole new level of where's this executed and why is this not performing what I want??? But I guess we indeed need another layer of abstraction/design pattern/paradigm in PHP, which is supposed to be simple, clean, fast, not like Java, or insert your clearly more preferred language here, which has all those cool features that we can't play with in PHP :( If you like so much coool things, just look at the mess that Zend Framework 2 is. And if you like AOP and want to help, can you debug and fix this please? https://github.com/symfony/symfony/issues/2679 my mortal skills aren't enough to understand the Security component to fix it. Maybe when PHP will have native support for the features needed to do a clean AOP implementation, I'll change my mind (for sure), or maybe that will happen faster then that. Who knows? :) Just my two cents from a non-academic / theoretic point of view. Best regards.
