load_app_class('user_model', 'user'); $user_model = new User_Model();
load_app_class('user_controller', 'user'); $user_controller = new User_Controller();In this example, `load_app_class` function loads a file named `user_controller.php` from the `user` package directory in the application folder. The resulting object is an instance of the `User_Controller` class. Package library: It is not possible to determine the package library using the `load_app_class` function alone. The package library depends on the naming conventions used by the developer for organizing their application files. However, it is common for developers to use a package name that corresponds to a subdirectory of the application directory. In the examples above, the `user` package corresponds to a subdirectory in the application folder named `user`.
