Defining extra constants CI 4

Hey

I am rewriting some of my smaller projects to get the hang of CI 4. But some things I am now rewriting I want to be able to reuse aftwerward without to much of a hassle. So I am trying to not meddle to much with the files allready included within CI 4 folders. One of those things I want to do is create my own little config with my own constants in there. But for the love of god I am unable to get it working.

It might be something stupid but if anyone has any working example i would be gratefull. Or if you have a better way of going about it i am all ears.

Just note I am in no way a experienced programmer.

You can create a class in the Config namespace and use it just like any other class.

PHP Code:

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class MyStuff extends BaseConfig
{
    define("FOO",  "something");

    public $bar = "Hello World.";

} 


Then when you want to use "MyStuff" you create an instance of it and use the public properties like any other class.

PHP Code:

<?php namespace App\Controllers;

class Home extends BaseController
{
    public function index()
    {
       $myStuff = new Config\MyStuff();
       echo $myStuff->bar;
    }
}
