Laravel is a modern PHP framework known for its elegant syntax, expressive APIs, and powerful tools like Eloquent ORM, Blade templating, and Artisan CLI.
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:
For example, to define a simple route, you can use:
Route::get('/welcome', function () { return view('welcome'); });
Migrations in Laravel are like version control for your database, allowing you to define and modify database tables easily.
To create a migration, follow these steps:
php artisan make:migration create_users_table
.database/migrations
.For instance, to create a users table, you would write:
Schema::create('users', function (Blueprint $table) { $table->id(); $table->string('name'); $table->timestamps(); });
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:
php artisan make:provider MyServiceProvider
.config/app.php
file under providers
.register()
and boot()
methods to bind services.For example:
public function register() { $this->app->singleton('MyService', function () { return new MyService(); }); }
Laravel provides a straightforward way to handle user authentication. It includes built-in features for user registration, login, and password resets.
To set up authentication, follow these steps:
composer require laravel/ui
to install the UI package.php artisan ui vue --auth
.npm install && npm run dev
to compile the assets.This will create routes, controllers, and views for user authentication. For example, the login route can be found in routes/web.php
:
Auth::routes();
Middleware in Laravel provides a convenient mechanism for filtering HTTP requests entering your application. It allows you to execute code before or after a request is processed.
To create and use middleware, follow these steps:
php artisan make:middleware CheckAge
.handle()
method to define the filtering logic.app/Http/Kernel.php
.For instance, here’s a simple middleware that checks user age:
public function handle($request, Closure $next) { return $request->age >= 18 ? $next($request) : redirect('home'); }
