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
model communicates with theUsertable.users - 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
-
A user visits
./posts -
The route sends the request to
.PostController -
retrieves posts using thePostControllermodel.Post - The controller passes the data to a Blade view.
- 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
}
}
