FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Installation
Install via Composer:
Quick Start
Usage
Basic Operations
Setting Services
Getting Services
Multiple Access Patterns
Lazy Service Resolution
Services defined as callables are automatically resolved when accessed:
Singleton Pattern
Use share() to ensure a service is resolved only once:
Raw Callables
Prevent automatic resolution when you need to store a callable as a value:
Service Providers
Organize service registration with providers:
Constructor Initialization
You can pre-populate the container:
Method Chaining
Most methods return $this for fluent interfaces:
Container-Aware Classes
Use the HasContainer trait to make classes container-aware:
API Reference
Container
__construct(array $entries = [])
Creates a new container instance, optionally with initial entries.
get(string $id): mixed
Retrieves a service from the container. Throws NotFoundException if the service doesn't exist.
Throws: NotFoundException
has(string $id): bool
Checks if a service exists in the container.
set(string $id, mixed $entry): static
Registers a service in the container. Returns $this for method chaining.
install(ServiceProviderInterface $provider): static
Installs a service provider. Returns $this for method chaining.
share(callable $entry): callable
Wraps a callable to ensure it's only resolved once (singleton pattern).
raw(callable $entry): callable
Wraps a callable to prevent automatic resolution when retrieved.
Exceptions
ContainerException
Base exception for container-related errors. Extends InvalidArgumentException and implements ContainerExceptionInterface.
NotFoundException
Thrown when a requested service is not found. Extends ContainerException and implements NotFoundExceptionInterface.
Interfaces
ServiceProviderInterface
Interface for service providers. Implement this to create modular service registration.
Methods:
provide(Container $container): void- Registers services with the container
KeepsContainer
Interface for container-aware classes. Use with the HasContainer trait.
Methods:
getContainer(): ?ContainerInterface- Gets the container instancesetContainer(ContainerInterface $container): void- Sets the container instance

- PHP >= 8.2
