File Uploads and Storage: Managing User Files

Laravel provides a unified API for working with file systems.

  ## Store uploaded file
  
  ```php
  $path = $request->file('avatar')->store('avatars', 'public');
  ```
  
  ## Get URL
  
  ```php
  $url = Storage::disk('public')->url($path);
  ```
  
  ## Storage flow
  
  ```mermaid

    A[Upload] --> B[Controller]
    B --> C[Storage API]
    C --> D{Disk}
    D -->|local| E[Local FS]
    D -->|s3| F[AWS S3]
  ```
  
  This makes it easy to switch between local and cloud storage.
  
  In the next tutorial, we will notify users using Laravel notifications.
