Config Helpers

The package exposes one helper.

config()

function config(): Config

Use it when you want the shared configuration store managed by Quantum DI.

use Quantum\Loader\Setup;

config()->import(new Setup('config', 'app'));

if (config()->has('app.debug')) {
    $debug = config()->get('app.debug');
}

Behavior:

1. checks whether Config::class is registered in DI
2. registers it if missing
3. returns the shared Config instance

What that means in practice

• repeated config() calls reuse the same store
• values written with set() are visible through later helper calls
• flush() resets the same shared instance instead of creating a second store

If you need an isolated config store for a narrow task, instantiate new Config() yourself instead of using the helper.
