$logger = $container->resolve(LoggerInterface::class);

---

Alias for resolve(). Resolve a service from the container.

Parameters:

• $abstract (string): The interface or class name to resolve

$service = $container->get(MyService::class);

---

has(string $id): bool

Check if a binding exists in the container.

Parameters:

• $id (string): The interface or class name or string to check
