Contracts
This project is a PHP interface library that provides a component interoperability layer. It consists of a set of framework-agnostic contracts and standardized definitions that enable different libraries to work together via a consistent contract.
The library focuses on providing minimal shared interfaces and API definitions, allowing software components to be used across different PHP projects regardless of the underlying framework. This approach decouples application logic from concrete framework implementations.
The project specifically covers service container abstraction and dependency injection standardization. By defining common interfaces for accessing service containers, it ensures interoperability between different container implementations and allows components to retrieve dependencies across various environments.
Features
- Dependency Injection Interoperability - Standardizes how objects interact with dependency injection containers to enable swapping of implementation libraries.
- Interface-Based Decoupling - Provides generic interfaces that allow services to remain compatible across different components and versions.
- PHP Interoperability Libraries - Provides a shared set of API definitions that enable decoupled components to be used across various PHP projects.
- PHP Standard Interface Implementations - Defines common interfaces and contracts ensuring PHP libraries can work together without framework dependencies.
- Interface Contracts for Classes - Defines minimal shared contracts that allow disparate components to interact without depending on concrete implementations.
- Service Container Interfaces - Establishes a consistent way for components to interact with a service container to retrieve dependencies.
- Dependency Injection Containers - Defines standard ways for objects to access services and containers to facilitate implementation swapping.
- Framework Agnostic Interfaces - Provides minimal shared interfaces that enable software components to be used across different PHP projects.
- Interoperability Layers - Provides a set of standardized definitions that enable different libraries to work together via a consistent contract.
- Logic Abstraction Interfaces - Creates a shared layer of interfaces enabling PHP libraries to communicate without tying them to a specific framework.
- Container Interface Standards - Provides standardized definitions for retrieving services from a container to ensure interoperability.
- Type-Safe API Contracts - Employs PHP type declarations to enforce a consistent API surface across different library versions.
