What this system is

Features

PSR-11 Container Interface and Exception Types

The library now provides the PSR-11 \ContainerInterface\ along with \ContainerExceptionInterface\ and \NotFoundExceptionInterface\. The container interface defines \get()\ and \has()\ methods, with the \get()\ method throwing the new exception interfaces. The exception interfaces extend \Throwable\ to align with modern PHP practices, and the \NotFoundExceptionInterface\ extends \ContainerExceptionInterface\ to distinguish between general container errors and missing entries.

Dependencies

Introduce PSR-11 Container Interface as a Composer dependency

The project now depends on the 'psr/container' package (version 2.0.x-dev), which provides the PSR-11 Common Container Interface. This dependency requires PHP 7.4.0 or higher and utilizes PSR-4 autoloading for the 'Psr\\Container' namespace mapped to the 'src/' directory.

php-fig/container was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.

About this page

  • The score is its most recent published measurement, taken on 26 September 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 707984727bd5b2b670e59559d3ed2500240cf875 — the exact code this score is about.
  • Scored under rubric-2026.09.15 — the same rubric and the same method as every other entry in this index.
  • Measured by watchdog.canine.dev using codehealth-analyzer preprod-a15879f6f801.
