container-interop tries to identify and standardize features in container
objects (service locators, dependency injection containers, etc.) to achieve
interoperability.

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 [1],
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.
