PSR-11 Usage
++++++++++++

  PSR-11 describes a common interface for dependency injection containers.

It is supported by an set of interfaces, that one may use in the code.

.. code-block:: php
   
   <?php
   
   namespace MyNamespace;
   
   // MyContainerInterface implements the PSR-7 ServerRequestInterface.
   // MyContainerInterface is more of a black hole than a real Container.
   class MyContainerInterface implements \Psr\Container\ContainerInterface {
       public function get($id) {}
       public function has($id) {}
   }
   
   ?>
