Explain MVC architecture.

MVC stands for Model, View, and Controller. It is a software design pattern used in Laravel to separate the application's logic into different components, making the code more organized and easier to maintain.

  • Model: The Model is responsible for handling the application's data and business logic. It interacts with the database, performs queries, and manages data. For example, a User model communicates with the users table.
  • View: The View is the presentation layer. It displays data to the user and contains the user interface. In Laravel, views are usually created using the Blade templating engine.
  • Controller: The Controller acts as a bridge between the Model and the View. It receives user requests, processes them, interacts with the Model if needed, and returns the appropriate View or response.

Example Flow

  1. A user visits /posts.
  2. The route sends the request to PostController.
  3. PostController retrieves posts using the Post model.
  4. The controller passes the data to a Blade view.
  5. The view displays the posts to the user.

Example in Laravel

// Route
Route::get('/posts', [PostController::class, 'index']);
            
// Controller
class PostController extends Controller
{
    public function index()
    {
        $posts = Post::all(); // Model
        return view('posts.index', compact('posts')); // View
    }
}
