Laravel MVC Architecture

🧩 Understanding MVC in Laravel
MVC is a design pattern that separates an application into three interconnected components:
Model: Manages the data and business logic.
View: Handles the presentation layer, displaying data to the user.
Controller: Acts as an intermediary between Model and View, processing user input and updating the Model.
In Laravel, MVC is implemented as follows:
Model: Represents database records and business logic. Laravel uses Eloquent ORM for database interactions.
View: Typically Blade templates that render HTML and display data.
Controller: Contains methods that handle user requests, interact with models, and return views.
🔄 MVC Workflow in Laravel
Routing: A user makes a request (e.g., visiting a URL).
Controller: The router directs the request to a specific controller method.
Model: The controller interacts with the model to retrieve or manipulate data.
View: The controller passes data to a view, which is rendered and returned to the user.
🛠️ Example: Displaying a Blog Post
Consider a simple example where a user wants to view a blog post.
Route: Defines the URL pattern and maps it to a controller method.
Route::get('/post/{id}', [PostController::class, 'show']);
Controller: Handles the request and fetches the data.
class PostController extends Controller { public function show($id) { $post = Post::find($id); return view('post.show', compact('post')); } }
Model: Represents the data structure.
class Post extends Model { protected $fillable = ['title', 'content']; }
View: Displays the data to the user.
<!-- resources/views/post/show.blade.php --> <h1>{{ $post->title }}</h1> <p>{{ $post->content }}</p>
✅ Benefits of MVC in Laravel
Separation of Concerns: Each component has a distinct responsibility, making the codebase more organized and maintainable.
Reusability: Models and views can be reused across different parts of the application.
Testability: Isolated components are easier to test.
Scalability: Facilitates scaling the application by allowing independent development of components.
