1. Create Controller in app/Http/Controllers
2. We can create multiple functions inside a controller
3. we can create multiple Controllers inside the controller folder

1. Naming Rule

Controllers should be in PascalCase/CapitalCase. They should be in singular case, no spacing between words, and end with "Controller". Also, each word should be capitalised (i.e. BlogController, not blogcontroller).

For example: BlogController, AuthController, UserController.

2. Steps

1. create the controller StudentController.php in app/Http/Controllers folder

2. add namespace namespace App\Http\Controllers;

3. import base class of laravel controller use App\Http\Controllers\Controller;

4. extend the Controller class from Controller using extend keyword;

                 namespace App\Http\Controllers;
                 use App\Http\Controllers\Controller;

                 class StudentController extends Controller {

                     
                 }
                

3. define variables and functions

                 namespace App\Http\Controllers;
                 use App\Http\Controllers\Controller;

                 class StudentController extends Controller {
                       public $mark; 
                       public function findGrade(){

                          echo 1;

                       }

                       public function findFee(){

                        echo 2;

                     }
                     
                 }
                

4. load view page

return view() is used for loading the view page. first parameter of view() is name of the view blade in resources/views

                public function findGrade(){

                        return view('blade_name');

               }
