**Utilize Laravel's Service Container for Contextual Binding**

Leverage Laravel's service container to define contextual bindings, allowing different implementations of an interface to be injected based on specific classes or scenarios. This is especially useful when you have multiple implementations of a service and need to resolve the appropriate one depending on where it's being used. To set this up, you can define contextual bindings within a service provider like so:

```php
use App\Contracts\PaymentInterface;
use App\Services\PayPalService;
use App\Services\StripeService;

public function register()
{
    $this->app->when(OrderController::class)
              ->needs(PaymentInterface::class)
              ->give(PayPalService::class);

    $this->app->when(SubscriptionController::class)
              ->needs(PaymentInterface::class)
              ->give(StripeService::class);
}
```

With this configuration, `OrderController` will automatically receive an instance of `PayPalService` when it requires `PaymentInterface`, while `SubscriptionController` will get `StripeService`. This approach promotes cleaner code, enhances flexibility, and adheres to the Dependency Inversion Principle, making your application easier to maintain and extend.
