On the SitePoint PHP blog today they've posted a new tutorial that reintroduces you to FuelPHP, the framework that was (sort of) the successor to the CodeIgniter framework. It was started by some of the ex-CI developers in an effort to make a more robust, yet simple PHP framework for PHP 5.3+.
As a PHP developer, I have been a consistent user of different PHP frameworks, mostly focusing on CakePHP. Recently, I felt the need to go framework shopping and I have many valid reasons for choosing FuelPHP. It has a built-in modular structure and complete flexibility with emphasis on community. Before Fuel, I was a CakePHP user and just like Cake, Fuel is a huge community driven framework.
The author walks you through the installation process (via the framework's own "oil" command line tool) and dives into some example code quickly after that. He shows how to create a simple "Hello World" route and generate the scaffolding (code generation for the MVC pieces) including migrations. He creates a simple "users" table and adds some authentication checking to the controller. Then in the view he sets up a simple login form, requesting username and password and outputting any errors that might pop up during the authentication process.
