   namespace App\Http\Controllers;

   class FileController extends BaseController
   {
       public function upload()
       {
           if (!$this->canUploadFiles()) {
               return redirect()->back()->with('error', 'File uploads are disabled.');
           }

           // Handle file upload logic here
       }
   }

• Centralized Logic: Common functionality is defined in one place, reducing code duplication.
• Ease of Maintenance: Updates to shared logic automatically apply to all child controllers.
• Improved Readability: Child controllers remain focused on specific actions, while shared concerns are handled in the Base Controller.

• Performance Improvement: Avoid redundant database queries by loading shared data once.
• Centralized Data Logic: Keep shared data in a single location for easy maintenance.
• Reusability: Access the same data instance anywhere in the application without reloading.

By using the singleton pattern in Laravel, you’ve optimized how shared data is managed and accessed across your application. This approach ensures efficient performance and consistent data usage, making it ideal for managing application-wide settings, preferences, or resource limits.
