Zend Framework

Zend Framework is one of the most powerful PHP5-based open source frameworks commonly used for the development of web applications and services. Strictly object-oriented, it is known for the robustness of MVC implementation and the “use-at-will” design concept that relies on the loosely coupled architecture. Zend Framework’s system components have few interdependencies and so may be used both separately and as a part of the extendable web framework, providing excellent productivity and stability to end-products.
