Kohana is a highly popular MVC (Model-View-Controller) framework, providing a modular and flexible development environment. Its main features include:
Installing the Kohana framework is quite simple. Just download the latest version of Kohana and extract it to your server. Then, follow these steps to set it up:

return array(
'default' => array(
