$config = Kohana::$config->load('date'); $config->set('timezone', 'America/New_York');
$config = Kohana::$config->load('database'); $config->set('default.username', 'new_user'); $config->set('default.password', 'new_password');In this example, the load method is used to load the configuration file for the "database" module, and the set method is called twice to update the value of the default.username and default.password options. The Kohana framework is a PHP web application framework that provides a set of libraries and conventions for building scalable, maintainable web applications. The Config class and its various methods, including config_set, are part of the Kohana Core package, which provides the base functionality for the framework.
