This is a basic and minimalist implementation of PSR-11 for config management and dependency injection.
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.
Follow the steps below:
- Set up the configuration files;
- Load the configuration;
- Optionally define the dependency injection);
