Zend Framework 101: Zend_Registry
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.
This article requires Zend Framework, downloadable from http://framework.zend.com. At time of writing, the current version of Zend Framework is 1.7.6.
