Core Components

Dependency Injection Container

The Container is a simple dependency injection container that allows you to register services and retrieve their instances.

Example:

use Leopard\Core\Container;

$container = new Container();

// Register a service
$container->set('logger', function () {
    return new Logger();
});

// Retrieve the service
$logger = $container->get('logger');

---

Routing

The Router allows you to define routes using attributes and handle HTTP requests.

Example:

use Leopard\Core\Router;
use Leopard\Core\Attributes\Route;

class TestController
{
    #[Route('/test', method: 'GET')]
    public function test(): string
    {
        return "Hello, world!";
    }
}

$router = new Router();
$response = $router->dispatch('/test', 'GET');
echo $response; // Outputs "Hello, world!"

---

Attributes

leopard-core supports PHP attributes for defining routes and other metadata.

Example:

use Leopard\Core\Attributes\Route;

#[Route('/user/{id}', method: 'GET')]
public function getUser(string $id): string
{
    return "User ID: $id";
}

---

Usage Examples

Loading Configuration

use Leopard\Core\Config;

$config = new Config();
$config->load(__DIR__ . '/config/app.yaml');

echo $config->get('database.host'); // Outputs 'localhost'

---

Testing

To run tests, use the following command:
