Pxxo is a set of PHP classes used to build self-supported and interoperable Web graphical components. These classes are packaged following PEAR rules.
Thanks to Pxxo, you can create Web graphical components (also called widgets) in order to build HTML pages as a hierarchy of simple components.
Each widget is a small Web application that can be easily integrated into an existing PHP application (not necessarily built with Pxxo) or into another widget.
In the end, this architecture can be used to build a complete Web application.
Besides, this architecture is based on a skeleton that helps to keep source code homogeneous.
