For those who have never heard of PRADO before, PRADO is a
component-based and event-driven programming framework for developing
Web applications in PHP. PRADO stands for Php Rapid Application
Development Object-oriented. PRADO was initially released in August
2004 as the grand prizer winner of the Zend coding contest and has
since been adopted by thousands of developers.

PRADO is best suitable for creating Web applications that are highly
user-interactive. It can be used to develop systems as simple as a
blog system to those as complex as a content management system (CMS)
or a complete e-commerce solution. Because PRADO promotes
object-oriented programming through its component-based methodology,
it fits extremely well for team work and enterprise development.
