Laravel is a popular PHP framework designed for web application development. It follows the Model-View-Controller (MVC) architectural pattern, promoting clean and organized code.

Key features of Laravel include:

  • Eloquent ORM: An intuitive ORM for database interaction.
  • Blade Templating Engine: A powerful templating engine for dynamic content.
  • Routing: Simplified routing for RESTful applications.
  • Artisan Console: Command-line tool for automating tasks.

For example, to define a simple route, you can use:

Route::get('/welcome', function () { return view('welcome'); });

  3. Define the schema in the generated migration file located in database/migrations.

Service providers are the central place for configuring and bootstrapping your application in Laravel. They are responsible for binding services into the service container.

To use a service provider, follow these steps:

  1. Create a new service provider using: php artisan make:provider MyServiceProvider.
  2. Register the provider in the config/app.php file under providers.
  3. Implement the register() and boot() methods to bind services.

For example:

public function register() { $this->app->singleton('MyService', function () { return new MyService(); }); }

Laravel provides a straightforward way to handle user authentication. It includes built-in features for user registration, login, and password resets.

To set up authentication, follow these steps:

  1. Run the command: composer require laravel/ui to install the UI package.
  2. Generate the authentication scaffolding using: php artisan ui vue --auth.
  3. Run npm install && npm run dev to compile the assets.

This will create routes, controllers, and views for user authentication. For example, the login route can be found in routes/web.php:

Auth::routes();

Middleware in Laravel provides a convenient mechanism for filtering HTTP requests entering your application. It allows you to execute code before or after a request is processed.

To create and use middleware, follow these steps:

  1. Generate middleware using: php artisan make:middleware CheckAge.
  2. In the middleware, implement the handle() method to define the filtering logic.
  3. Register the middleware in app/Http/Kernel.php.

For instance, here’s a simple middleware that checks user age:

public function handle($request, Closure $next) { return $request->age >= 18 ? $next($request) : redirect('home'); }
