Laravel is a great PHP framework for developing anything from simple websites to complicated applications. We are currently using it on a rather complex system for one of our clients and we are so far really pleased with it.
With the introduction of version 4, there is incredible flexibility built into the framework to allow us to control everything from Navigation URLs, data base management, security and user account and how we manage the templates for the user interface.
Still early days, but so far, so good. If you have never used Laravel, but are looking for the next tool to try out, we’d certainly recommend giving it a shot: http://laravel.com/
