Introduction
In this article in the Zend Framework 101 series I will introduce you to the Zend_Registry class. This class used is to allow you manage variables and objects in the global application namespace. This is used as an alternative to using global variables in PHP. I will show you how to use the Zend_Registry class and also provide a practical example of where it would be useful to use the registry.
When you register a variable it is only available for the duration of the current request / script execution.
