# Extending Functionality

You can extend Curtain's functionality in several ways. Here's how to add custom features:

* Extending the Service:

```php
namespace App\Services;

use Daycode\Curtain\Services\CurtainService;

class ExtendedCurtainService extends CurtainService
{
    public function enableWithNotification(array $options = []): void
    {
        // Call parent implementation
        parent::enable($options);

        // Add custom notification logic
        if (isset($options['notify'])) {
            $this->sendNotifications($options['notify']);
        }
    }

    protected function sendNotifications(array $channels): void
    {
        foreach ($channels as $channel) {
            // Implement notification logic
            match ($channel) {
                'slack' => $this->notifySlack(),
                'email' => $this->notifyEmail(),
                default => null
            };
        }
    }
}
```

* Register your extended service:

```php
namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Services\ExtendedCurtainService;

class AppServiceProvider extends ServiceProvider
{
    public function register(): void
    {
        $this->app->singleton('curtain', function ($app) {
            return new ExtendedCurtainService();
        });
    }
}
```
