The official PHP-FIG repository holding the PSR-11 Container Interface, a set of PHP interfaces describing dependency injection containers. It provides only abstractions, not an implementation, so containers can be interoperable across frameworks.

Use cases

• standardize dependency injection container interfaces in a PHP framework
• make my DI container PSR-11 compliant
• type-hint against a container interface instead of a concrete implementation
• swap DI containers without changing application code
• build interoperable PHP libraries that accept any PSR-11 container

When to choose

• you are building a PHP framework or library that should work with any compliant DI container
• you want to make your container implementation PSR-11 compatible
• you need a stable, FIG-standardized interface to type-hint against

When to avoid

• you need an actual working dependency injection container implementation
• your project does not use PHP
• you want features like auto-wiring or configuration out of the box
