A registry is a container for storing objects and values in the application space. By storing the value in a registry, the same object is always available throughout your application. This mechanism is an alternative to using global storage.
The typical method to use registries with Zend Framework is through static methods in the
Zend_Registry class. Alternatively, the registry can be used as an
array object, so you can access elements stored within it with a convenient array-like
interface.
