Laravel Project Structure
Important folders:

- public/ (entry point)
MVC Architecture in Laravel
Laravel follows MVC:
Model:

Routing in Laravel
Routes define how your application responds to requests.
Example:
Route::get('/home', function () {
return view('home');

Routes are defined in:
routes/web.php
Controllers in Laravel
Controllers manage application logic.
php artisan make:controller UserController
Example:
class UserController extends Controller {
public function index() {
return "Users Page";
}
}
Blade Templating Engine
Laravel uses Blade for views.
<h1>Hello {{ $name }}</h1>
Features:
- Template inheritance
- Control structures
- Clean syntax
Database and Migrations
Laravel simplifies database management using migrations.
php artisan make:migration create_users_table
Example:
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->timestamps();
});
Run migration:
php artisan migrate
Eloquent ORM
Eloquent is Laravel’s ORM for database interaction.
