What is PRADO?
The PRADO framework is an open source programming framework for creating professional web applications. PRADO means PHP Rapid Application Development Object-oriented. It is component-based and allows event-driven programming. PRADO, which has a configurable and pluggable modular architecture, supports Ajax components and offers customizable and localizable error handling, generic caching modules and selective output caching.
This free PHP framework only requires a web server with PHP 5.1.0 or later. Granted with a revised BSD License, PRADO is suitable for developing both open source and commercial applications.
