Container Interoperability
container-interop tries to identify and standardize features in container objects (service locators, dependency injection containers, etc.) to achieve interopererability.
Through discussions and trials, we try to create a standard, made of common interfaces but also recommendations.
If PHP projects that provide container implementations begin to adopt these common standards, then PHP applications and projects that use containers can depend on the common interfaces instead of specific implementations. This facilitates a high-level of interoperability and flexibility that allows users to consume any container implementation that can be adapted to these interfaces.
The work done in this project is not officially endorsed by the PHP-FIG, but it is being worked on by members of PHP-FIG and other good developers. We adhere to the spirit and ideals of PHP-FIG, and hope this project will pave the way for one or more future PSRs.
Installation
You can install this package through Composer:
{
"require": {
"container-interop/container-interop": "~1.0"
}
}
The packages adheres to the SemVer specification, and there will be full backward compatibility between minor versions.
Standards
Available
ContainerInterface
. Description Meta Document. Describes the interface of a container that exposes methods to read its entries.- Delegate lookup feature. Meta Document. Describes the ability for a container to delegate the lookup of its dependencies to a third-party container. This feature lets several containers work together in a single application.

Workflow
Everyone is welcome to join and contribute.
The general workflow looks like this:
- Someone opens a discussion (GitHub issue) to suggest an interface
- Feedback is gathered
- The interface is added to a development branch
- We release alpha versions so that the interface can be experimented with
- Discussions and edits ensue until the interface is deemed stable by a general consensus
- A new minor version of the package is released
We try to not break BC by creating new interfaces instead of editing existing ones.
While we currently work on interfaces, we are open to anything that might help towards interoperability, may that be code, best practices, etc.
