PSR-11 Support

container-interop/container-interop 1.2.0 modifies its codebase to extend interfaces from psr/container (the official interfaces for PSR-11). If you are on a pre-3.3.0 version of zend-servicemanager, update your project, and receive container-interop 1.2, then zend-servicemanager can already act as a PSR-11 provider!

zend-servicemanager 3.3.0 requires at least version 1.2 of container-interop, and also requires psr/container 1.0 to explicitly signal that it is a PSR-11 provider, and to allow removal of the container-interop dependency later.

Version 4.0 will require only psr/container, and will update the various factory interfaces and exception implementations to typehint against the PSR-11 interfaces, which will require changes to any implementations you have. In the meantime, you can duck-type the following factory types:

• Zend\ServiceManager\Factory\FactoryInterface: use a callable with the following signature:

  function (
      \Psr\Container\ContainerInterface $container,
      string $requestedName,
      array $options = null
  )
  

• Zend\ServiceManager\Factory\DelegatorFactoryInterface: use a callable with the following signature:

  function (
      \Psr\Container\ContainerInterface $container,
      string $name,
      callable $callback,
      array $options = null
  )
  

• Zend\ServiceManager\Initializer\InitializerInterface: use a callable with the following signature:

  function (
      \Psr\Container\ContainerInterface $container,
      $instance
  )
  

Abstract factories can not be duck typed, due to the additional canCreate() method.

You can also leave your factories as-is for now, and update them once zend-servicemanager v4.0 is released, at which time we will be providing tooling to help migrate your factories to PSR-11.
