Setting Up Laravel

Prerequisites

Before you begin, ensure you have the following installed on your system:

  • PHP: Version 7.3 or higher.
  • Composer: A dependency manager for PHP.
  • Database: MySQL, PostgreSQL, SQLite, or SQL Server.

Installing Laravel

  1. Install Composer:

    • If you haven’t already, download and install Composer from getcomposer.org.

  2. Create a New Laravel Project:

    • Open your terminal or command prompt and run the following command:
      composer create-project --prefer-dist laravel/laravel blog
    • This will create a new Laravel project in a directory named blog.

  3. Navigate to Your Project Directory:

    cd blog

  4. Serve Your Application:

    • Start the development server by running:
      php artisan serve
    • Open your browser and navigate to http://localhost:8000 to see your new Laravel application in action.

Understanding Laravel Basics

Directory Structure

Laravel’s directory structure is designed to be intuitive. Here are some key directories you should know:

  • app/: Contains the core application code (controllers, models, etc.).
  • config/: Holds configuration files.
  • database/: Contains database migrations, factories, and seeders.
  • public/: The web server root directory.
  • resources/: Contains views, CSS, and JavaScript assets.
  • routes/: Defines application routes.
  • storage/: Stores logs, compiled templates, and other generated files.

Routing

Laravel’s routing system is straightforward. Routes define how your application responds to requests.

  • Open the routes/web.php file and add a route:
    Route::get('/hello', function () {
    return 'Hello, World!';
});
  • Visit http://localhost:8000/hello to see your route in action.

Controllers

Controllers handle the logic of your application. They group related route logic into a class.

  1. Create a Controller:

    php artisan make:controller HelloController

  2. Define a Method in the Controller:

    • Open app/Http/Controllers/HelloController.php and add a method:
      public function index() {
    return 'Hello from the controller!';
}

  3. Update the Route:

    • Modify routes/web.php to use the controller:
      Route::get('/hello', [HelloController::class, 'index']);

Views

Views are the presentation layer of your application. Laravel uses Blade as its templating engine.

  1. Create a View:

    • In resources/views, create a file named hello.blade.php:
      <!DOCTYPE html>
<html>
<head>
    <title>Hello</title>
</head>
<body>
    <h1>{{ $message }}</h1>
</body>
</html>

  2. Return the View from the Controller:

    • Modify HelloController to pass data to the view:
      public function index() {
    return view('hello', ['message' => 'Hello from Blade!']);
}

Working with Databases

Laravel makes database interactions simple with Eloquent ORM.

Migrations

Migrations are version control for your database.

  1. Create a Migration:

    php artisan make:migration create_posts_table

  2. Define the Table Structure:

    • Open the migration file in database/migrations and define the columns:
      public function up() {
    Schema::create('posts', function (Blueprint $table) {
        $table->id();
        $table->string('title');
        $table->text('content');
        $table->timestamps();
    });
}

  3. Run the Migration:

    php artisan migrate

Eloquent Models

Eloquent makes working with databases elegant and simple.

  1. Create a Model:

    php artisan make:model Post

  2. Use the Model:

    • Open app/Models/Post.php and define any necessary relationships or custom methods.

Conclusion

Laravel is an excellent PHP framework for beginners due to its elegant syntax, comprehensive documentation, and built-in tools. By following this quick start guide, you’ll be well on your way to developing robust web applications with Laravel. The journey of learning a new framework can be challenging, but with Laravel, you’ll find it both enjoyable and rewarding.
