Composer - Autoload and PSR-0 vs PSR-4

[LeoFelipe]

I'm beginning to study Composer and am developing a system where I separate the files core application files, as follows:

/root

  |-- /src

        |-- /App

              |-- /DBConfig

              |-- /Controller

              |-- /Model

        |-- /Core

              |-- /Helper

              |-- /Controller

              |-- /Model

So, to set this setting in composer.json file and get access to all classes both /App much /Core would be this way?

"autoload" : {

    "psr-X" : {

        "App\\" : "/src",

        "Core\\" : "/src"

    }

}

Or is there a more correct way?

I have also read about PSR-0 vs PSR-4 and I am still somewhat in doubt which one to use. In my case what should I implement, PSR-0 or PSR-4?

With the layout you have you should tell composer that you are using psr-0.

 

Then, as long as you are using namespaces that coincide with your directory structure your classes will be autoloaded.
