marek-baron/config
==================

[](#marek-baronconfig)

[![CI](https://github.com/marek-baron/config/actions/workflows/ci.yml/badge.svg)](https://github.com/marek-baron/config/actions)

Lightweight, dependency-free PHP configuration library.

Features
--------

[](#features)

- Simple key access using dot notation (db.host)
- Immutable config (with() returns a cloned instance)
- Merge multiple config sources via ConfigAggregator
- Provider support for files, callables, classes, or arrays
- No external dependencies

Installation
------------

[](#installation)

composer require marek-baron/config

Config example
--------------

[](#config-example)

```
$config = new Config([
'db' => ['host' => 'localhost', 'port' => 3306],
'app' => ['debug' => false],
]);

echo $config->get('db.host');
$newConfig = $config->with('app.debug', true); //Immutable!

var_dump($config->get('app.debug'));     // false
var_dump($newConfig->get('app.debug'));  // true
```

ConfigAggregator example
------------------------

[](#configaggregator-example)

```
use MarekBaron\Config\ConfigAggregator;

$aggregator = new ConfigAggregator([
    __DIR__ . '/config/global.php',
    __DIR__ . '/config/local.php',
    fn() => ['cache' => ['enabled' => true]],
]);

$config = $aggregator->load();

echo $config->get('cache.enabled'); // true
```

ConfigProviderInterface example

```
namespace App\Domain\Module;

use MarekBaron\Config\ConfigProviderInterface;

class ConfigProvider implements ConfigProviderInterface
{
    public function __invoke(): array
    {
        return [
            'factories' => [
                UserLoginHandler::class => UserLoginHandlerFactory::class,
            ],
            'routes' => [
                // your routes
            ],
            // anything else
        ];
    }
}
```

----------------------
