README
This is a basic and minimalist implementation of PSR-11 for config management and dependency injection.
Basics
PSR-11, or "PHP Standard Recommendation 11," is a PHP specification that outlines a common interface for implementing dependency injection containers in PHP applications. Dependency injection is a design pattern that allows objects to receive their dependencies from an external source, instead of creating them internally.
Here's a summary of PSR-11:
-
Purpose: PSR-11 provides a standardized approach to implementing and using dependency injection containers in PHP applications.
-
Container Interface: PSR-11 defines the Psr\Container\ContainerInterface, which includes methods for retrieving instances of objects (dependencies) from the container.
-
Container Operations: The interface includes methods such as get($id) to retrieve an instance by its identifier (usually a string), has($id) to check if an instance exists in the container, and set($id, $value) to manually register an instance with the container.
-
Implementing Containers: Developers can create their own containers by implementing the ContainerInterface and providing the necessary methods for managing and retrieving instances.
-
Interoperability: PSR-11 promotes interoperability between different PHP frameworks and libraries by providing a common interface. Applications built using PSR-11 containers can switch between different containers without needing to modify the application code.
-
Autowiring: While PSR-11 does not explicitly define autowiring (automatic resolution of dependencies), containers implementing this specification can choose to include autowiring functionality if desired.
-
Extension: PSR-11 can be extended by other PSR specifications to provide additional features or standards related to dependency injection.
In summary, PSR-11 standardizes the way dependency injection containers are implemented and used in PHP, promoting code reusability, flexibility, and interoperability between different components of PHP applications.
How to Use This Component
Follow the steps below:
- Set up the configuration files;
- Load the configuration;
- Optionally define the dependency injection);
