Learn LARAVEL with Real Code Examples

Updated Nov 27, 2025

Explain

Laravel simplifies common tasks like routing, authentication, sessions, caching, and database interactions.

It uses the MVC (Model-View-Controller) design pattern for structured, maintainable code.

Includes an ORM called Eloquent for easy database operations.

Provides built-in tools for testing, queues, events, and API development.

Supports blade templating engine for dynamic, clean views and components.

Core Features

MVC architecture

Routing and controllers

Eloquent ORM and database migrations

Blade templating

Queues, events, and task scheduling

Basic Concepts Overview

Routes - map URLs to controllers or closures

Controllers - handle request logic

Models - represent database tables with Eloquent

Views - Blade templates for rendering HTML

Migrations - version control for database schema

Project Structure

app/ - core application code (Models, Controllers, Services)

resources/ - views (Blade templates), assets, translations

routes/ - route definitions

database/ - migrations, seeders, factories

config/ - application configuration files

Building Workflow

Define routes in `routes/web.php` or `routes/api.php`

Create controllers with `php artisan make:controller`

Define models and relationships using Eloquent

Build Blade templates for frontend views

Use migrations to manage database schema changes

Difficulty Use Cases

Beginner: Static website with simple routing

Intermediate: CRUD app with Eloquent models and controllers

Advanced: API with authentication, queues, and caching

Expert: Multi-tenant SaaS platform with broadcasting/events

Architect: Large enterprise application with microservices integration

        return view('counter', ['count' => $count]);
    }

    public function increment(Request $request) {
        $count = $request->session()->get('count', 0) + 1;
        $request->session()->put('count', $count);
        return redirect('/counter');
    }

    public function decrement(Request $request) {
        $count = $request->session()->get('count', 0) - 1;
        $request->session()->put('count', $count);
        return redirect('/counter');

<!DOCTYPE html>
<html>
<head><title>Laravel Counter</title></head>
<body>
    <h2>Counter: {{ $count }}</h2>
