FuelPHP

FuelPHP is a MVC (Model-View-Controller) framework that was designed from the ground up to build scalable web applications written in PHP. Out-of-the-box, FuelPHP supports HVMC as a part of its arcitecture. The Hierarchical-Model-View-Controller (HMVC) pattern is a direct extension to the MVC pattern that manages to solve many of the scalability issues when building applications. HMVC is a collection of traditional MVC triads operating as one application. Each triad is completely independent and can execute without the presence of any other. All requests made to triads must use the controller interface, never loading models or libraries outside of their own domain. FuelPHP is released as a free and open source framework under the MIT License and can be used for commercial and personal projects alike.
