1. What is Laravel?

Laravel is an open-source PHP framework designed to make web development easier and more efficient. It follows the Model-View-Controller (MVC) architectural pattern, which separates application logic from the user interface.

Key Features of Laravel:

• Elegant Syntax: Clean and readable code.
• Blade Templating Engine: Efficient front-end development.
• Eloquent ORM: Easy database handling.
• Authentication System: Built-in user authentication.
• API Development: Support for RESTful APIs.
• Task Scheduling: Automate tasks using the scheduler.

2. Why Use Laravel?

Laravel simplifies web development and offers several benefits:
✔ Rapid development with pre-built functions.
✔ Built-in security mechanisms like CSRF protection.
✔ Scalability for small to enterprise-level applications.
✔ Seamless third-party service integration using system integration services.

---

3. Setting Up Laravel

Before you begin, ensure your system meets the following requirements:

System Requirements

• PHP (>= 8.0)
• Composer (PHP dependency manager)
• MySQL or SQLite
• Node.js & NPM (for front-end assets)

Installation Steps

1. Install Composer
   Download and install Composer from https://getcomposer.org/.
2. Create a New Laravel Project
   Open the terminal and run:shCopyEditcomposer create-project --prefer-dist laravel/laravel myLaravelApp cd myLaravelApp
3. Start the Laravel Development ServershCopyEditphp artisan serve Laravel will run on http://127.0.0.1:8000.

---

4. Laravel Directory Structure

After installation, Laravel generates a structured directory layout:

• app/ – Application logic (Models, Controllers).
• routes/ – Route definitions.
• resources/views/ – Blade templates.
• database/ – Migrations and seeders.
• config/ – Configuration files.

---

5. Routing in Laravel

Routes define how Laravel handles incoming requests.

Basic Routing Example

Define a simple route in routes/web.php:

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

Visit http://127.0.0.1:8000/welcome to see the output.

---

6. Controllers and Middleware

Creating a Controller

Run the following command to create a controller:

shCopyEditphp artisan make:controller PageController

Define a function in app/Http/Controllers/PageController.php:

phpCopyEditnamespace App\Http\Controllers;

use Illuminate\Http\Request;

class PageController extends Controller
{
    public function about()
    {
        return view('about');
    }
}

Define a route in routes/web.php:

phpCopyEditRoute::get('/about', [PageController::class, 'about']);

---

7. Blade Templating Engine

Laravel uses Blade for templating.

Example Blade Template (resources/views/about.blade.php)

bladeCopyEdit@extends('layouts.app')

@section('content')
<h1>About Us</h1>
<p>Welcome to our Laravel application.</p>
@endsection

---

8. Database Management with Eloquent ORM

Laravel provides Eloquent ORM for database interactions.

Creating a Model and Migration

shCopyEditphp artisan make:model Post -m

Edit the migration file in database/migrations/:

phpCopyEditSchema::create('posts', function (Blueprint $table) {
    $table->id();
    $table->string('title');
    $table->text('body');
    $table->timestamps();
});

Run migrations:

shCopyEditphp artisan migrate

---

9. Laravel Authentication

Use Laravel Breeze for authentication:

shCopyEditcomposer require laravel/breeze --dev
php artisan breeze:install
npm install && npm run dev
php artisan migrate

This creates login and registration routes automatically.

---

10. API Development in Laravel

Laravel supports API development using JSON responses.

Creating an API Controller

shCopyEditphp artisan make:controller ApiController

Define an API route in routes/api.php:

phpCopyEdituse App\Http\Controllers\ApiController;
Route::get('/data', [ApiController::class, 'getData']);

---

11. System Integration Services in Laravel

System integration services help Laravel applications connect with third-party services like payment gateways, CRMs, and ERPs.

Example: Integrating a Payment Gateway

Install Stripe SDK:

shCopyEditcomposer require stripe/stripe-php

Configure Stripe in .env:

envCopyEditSTRIPE_KEY=your-stripe-key
STRIPE_SECRET=your-stripe-secret

Create a payment controller:

phpCopyEdituse Stripe\Stripe;
use Stripe\Charge;

class PaymentController extends Controller {
    public function charge(Request $request) {
        Stripe::setApiKey(env('STRIPE_SECRET'));
        $charge = Charge::create([
            "amount" => 1000,
            "currency" => "usd",
            "source" => $request->stripeToken,
            "description" => "Test Payment"
        ]);
        return response()->json($charge);
    }
}
