What is Laravel?

Laravel is an open-source PHP framework designed for web application development. It follows the Model-View-Controller (MVC) architectural pattern, making it easy to organize code and separate concerns. Laravel comes with built-in features like routing, authentication, and database migrations, which streamline the development process.

Key Features of Laravel

Eloquent ORM: A powerful object-relational mapper that makes database interactions intuitive and efficient.
Blade Templating Engine: A lightweight yet powerful templating engine for creating dynamic views.
Artisan CLI: A command-line interface that automates repetitive tasks like generating boilerplate code.
Migrations: A version control system for databases, allowing you to modify and share database schemas.
Security: Built-in features like CSRF protection, password hashing, and encryption ensure your application is secure.

Getting Started with Laravel

To get started with Laravel, you'll need to install it using Composer, a dependency manager for PHP. Follow these steps:

composer create-project --prefer-dist laravel/laravel blog

This command creates a new Laravel project named blog. Navigate to the project directory and start the development server:

cd blog
php artisan serve

Visit http://localhost:8000 in your browser to see the default Laravel welcome page.

Creating a Simple Route and View

Laravel makes it easy to define routes and render views. Let's create a simple route that displays a welcome message.

Open the routes/web.php file and add the following code:

Route::get('/welcome', function () {
    return view('welcome', ['message' => 'Hello, Laravel!']);
});

Create a new Blade view file named welcome.blade.php in the resources/views directory:

<!DOCTYPE html>
<html>
<head>
    <title>Welcome</title>
</head>
<body>
    <h1>{{ $message }}</h1>
</body>
</html>

Now, visit http://localhost:8000/welcome to see the welcome message.

Database Migrations and Eloquent ORM

Laravel's migration system allows you to define database schemas using PHP code. Let's create a migration for a posts table:

php artisan make:migration create_posts_table

Open the generated migration file in the database/migrations directory and define the schema:

public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->id();
        $table->string('title');
        $table->text('content');
        $table->timestamps();
    });
}

Run the migration to create the table:

php artisan migrate

With Eloquent ORM, you can interact with the posts table using a model. Create a Post model:

php artisan make:model Post

Now, you can use the model to create, retrieve, update, and delete records:

$post = new Post();
$post->title = 'My First Post';
$post->content = 'This is the content of my first post.';
$post->save();

Conclusion

Laravel is a powerful and versatile framework that simplifies web application development. With its elegant syntax, built-in features, and extensive documentation, Laravel is an excellent choice for developers of all skill levels. By following this guide, you've learned the basics of Laravel, including routing, views, migrations, and Eloquent ORM. Start building your next project with Laravel today!
