How to use constant defined in another file?

Question

Let’s say I have two files:

App/Version.php

<?php

namespace App;
const VERSION = "0.1.0";

App/Http/Controllers/AppController.php

namespace App\Http\Controllers;

use const App\VERSION;

class AppController extends Controller
{
    public function version()
    {
        return VERSION;
    }
}

With this, I’ve got "Undefined constant 'App\VERSION'" when I call AppController@version route.

I use composer. Probably, the question is about how to autoload constant...

Do you use composer for autoloading or you just require the file? — Marcin Nabiałek, Dec 19 '17 at 19:45

You can have a third file, which is included in those 2. Usually such file is called config.php or init.php

I use composer. I don't use `require`. – zhekaus Dec 19 '17 at 19:56
