Let us continue our work on the Students controller and build an action that would retrieve information about all the students in our students table, present in the controllers/students.php file:

public function get($id=null){
  $this->view->student_data = $this->model->getStudents();
  $this->view->render('students/get');
}

public function getStudents...
