Laravel Getting Started Example
What is Laravel?
Laravel is a PHP framework designed for fast and easy building of web applications. It provides a range of powerful features that allow developers to focus on business logic without worrying about the underlying infrastructure.
Install Laravel
- Install Composer (PHP Package Manager).
- Use Composer to install Laravel CLI globally:
composer global require laravel/installer. - Run
laravel new my-appin the project directory to create a new application.
Create a route
Routing defines the relationship between URLs and processing functions in a web application. Create a route in routes/web.php :
<code class="php">Route::get('/welcome', function () { return view('welcome'); });</code>Write a view
The view contains HTML and PHP code to render the application's interface. Create a view in resources/views/welcome.blade.php :
<code class="php"> <title>Welcome</title> <h1 id="欢迎来到Laravel">欢迎来到Laravel！</h1> </code>
Run the application
Run php artisan serve in the project directory to start the development server. Then visit http://localhost:8000/welcome in your browser to view the view.
Database integration
Laravel provides out-of-the-box integration with MySQL, Postgres, and other databases. Use migration to create and modify database tables:
<code class="php">php artisan make:migration create_users_table php artisan migrate</code>
Models and controllers
The model represents an entity in the database and the controller processes HTTP requests.
Create a model in app/Models/User.php :
<code class="php">class User extends Model { // ... }</code> Create a controller in app/Http/Controllers/UserController.php :
<code class="php">class UserController extends Controller { public function index() { $users = User::all(); return view('users.index', ['users' => $users]); } }</code>The above is the detailed content of Laravel Introduction Example.
