Laravel is one of the most popular PHP frameworks, known for its elegant syntax and powerful features. This module will guide you through the basics of getting started with Laravel, from installation to creating your first application.

Introduction to Laravel

Laravel is a web application framework with expressive, elegant syntax. It aims to make the development process a pleasing one for the developer without sacrificing application functionality. Laravel eases common tasks such as routing, authentication, sessions, and caching.

Key Features of Laravel:

Eloquent ORM: An advanced PHP implementation of the active record pattern.
Blade Templating Engine: A simple yet powerful templating engine.
Artisan CLI: A command-line interface for common tasks.
Routing: Simple and expressive routing.
Middleware: Filtering HTTP requests.
Security: Protection against common vulnerabilities.

Setting Up Laravel

Prerequisites:

PHP >= 7.3
Composer (Dependency Manager for PHP)
A web server (Apache, Nginx, etc.)
A database (MySQL, PostgreSQL, SQLite, etc.)

Step-by-Step Installation:

Install Composer: If you haven't installed Composer yet, you can download and install it from getcomposer.org.
Create a New Laravel Project: Open your terminal and run the following command:
```
composer create-project --prefer-dist laravel/laravel myLaravelApp
```
This command will create a new Laravel project in a directory named myLaravelApp.
Navigate to Your Project Directory:
```
cd myLaravelApp
```
Serve the Application: Laravel includes a local development server. You can start it using:
```
php artisan serve
```
By default, the application will be accessible at http://localhost:8000.

Laravel Directory Structure

Understanding the directory structure is crucial for working efficiently with Laravel. Here are some key directories and their purposes:

app/: Contains the core code of your application (models, controllers, etc.).
bootstrap/: Contains the application bootstrapping script.
config/: Contains all the configuration files.
database/: Contains database migrations, model factories, and seeds.
public/: The entry point for the application, contains the index.php file.
resources/: Contains views, raw assets (CSS, JS), and language files.
routes/: Contains all route definitions.
storage/: Contains compiled Blade templates, file-based sessions, file caches, and other files generated by the framework.
tests/: Contains automated tests.
vendor/: Contains Composer dependencies.

Creating Your First Route

Routes in Laravel are defined in the routes/web.php file. Let's create a simple route that returns a view.

Example:

Define a Route: Open routes/web.php and add the following code:

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

Create a View: Laravel comes with a default welcome.blade.php view located in resources/views. You can modify this file or create a new one.
Access the Route: Open your browser and navigate to http://localhost:8000. You should see the welcome page.

Creating a Controller

Controllers are responsible for handling the logic of your application. Let's create a simple controller.

Example:

Generate a Controller: Use the Artisan CLI to generate a controller:
```
php artisan make:controller HomeController
```

Define a Method in the Controller: Open app/Http/Controllers/HomeController.php and add a method:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    public function index()
    {
        return view('home');
    }
}

Define a Route for the Controller: Open routes/web.php and add:
```
Route::get('/home', [HomeController::class, 'index']);
```

Create a View for the Controller: Create a new file resources/views/home.blade.php and add some HTML content:

<!DOCTYPE html>
<html>
<head>
    <title>Home Page</title>
</head>
<body>
    <h1>Welcome to the Home Page</h1>
</body>
</html>

Access the Route: Open your browser and navigate to http://localhost:8000/home. You should see the home page.
