Simple Counter App — Laravel Code

Demonstrates a simple Laravel controller and routes for a counter using session for state persistence.

<?php

// routes/web.php
use IlluminateSupportFacadesRoute;
use AppHttpControllers\CounterController;

Route::get('/counter', [CounterController::class, 'show']);
Route::post('/counter/increment', [CounterController::class, 'increment']);
Route::post('/counter/decrement', [CounterController::class, 'decrement']);
Route::post('/counter/reset', [CounterController::class, 'reset']);

// app/Http/Controllers/CounterController.php
namespace AppHttpControllers;
use IlluminateHttpRequest;

class CounterController extends Controller {
	public function show(Request $request) {
		$count = $request->session()->get('count', 0);
		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');
	}

	public function reset(Request $request) {
		$request->session()->put('count', 0);
		return redirect('/counter');
	}
}

Laravel Language Guide

Laravel is an open-source PHP web framework designed for building modern, scalable, and maintainable web applications with expressive syntax, following MVC architecture and emphasizing developer productivity.

Primary Use Cases

▸Building modern web applications
▸Creating RESTful APIs
▸Developing SaaS platforms
▸Implementing authentication and authorization systems
▸Rapid prototyping and MVP development

Notable Features

▸Eloquent ORM for database abstraction
▸Blade templating engine
▸Routing and middleware support
▸Artisan CLI for automation tasks
▸Built-in authentication, authorization, and security features

Origin & Creator

Created by Taylor Otwell in 2011 and maintained by the Laravel community.

Industrial Note

Laravel is widely used in small-to-large web applications, SaaS platforms, and API-driven systems where rapid development and maintainable code are essential.

Quick 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

Learning Path

▸Week 1: PHP basics and MVC concepts
▸Week 2: Routing, controllers, and views
▸Week 3: Eloquent ORM and database migrations
▸Week 4: Authentication, middleware, and security
▸Week 5: Queues, events, API development, and testing

Practical Examples

▸Building a blog with authentication and comments
▸Developing a REST API for a mobile app
▸Implementing user roles and permissions
▸Scheduling tasks using Laravel scheduler
▸Building a real-time chat app using broadcasting

Comparisons

▸Laravel vs Symfony -> Laravel is more opinionated and faster to start; Symfony is more modular
▸Laravel vs CodeIgniter -> Laravel has modern features and Eloquent ORM; CI is lightweight
▸Laravel vs CakePHP -> Laravel offers better modern tooling and community support
▸Laravel vs Yii -> Laravel has expressive syntax and large ecosystem
▸Laravel vs Node.js frameworks -> Laravel is PHP-based and opinionated; Node.js offers JavaScript runtime flexibility

Strengths

▸Expressive and clean syntax for rapid development
▸Strong community and ecosystem
▸Scalable for small apps to enterprise solutions
▸Built-in security and testing features
▸Extensible via packages and modules

Limitations

▸Performance can be lower than micro-frameworks for extremely high-load apps
▸Monolithic structure may be overkill for very small projects
▸Requires PHP knowledge and modern PHP versions
▸Learning curve for advanced features like queues and broadcasting
▸Dependent on PHP runtime and environment setup

When NOT to Use

▸Very small static websites without dynamic features
▸Projects not using PHP
▸Applications needing extremely low-latency microservices
▸When you want a zero-dependency lightweight framework
▸Projects where learning curve for MVC is prohibitive

Cheat Sheet

▸php artisan make:controller -> create a controller
▸php artisan make:model -> create a model
▸php artisan migrate -> run database migrations
▸php artisan serve -> start development server
▸php artisan tinker -> interactive console for testing

FAQ

▸Is Laravel free? -> Yes, open-source under MIT License
▸Does Laravel require PHP? -> Yes, PHP 8+ recommended
▸Can Laravel be used for APIs? -> Yes, with API routes and Sanctum/Passport
▸Does Laravel support multiple databases? -> Yes, via Eloquent configuration
▸Is Laravel suitable for enterprise apps? -> Yes, with proper architecture and scaling

30-Day Skill Plan

▸Master Eloquent ORM relationships and queries
▸Use Blade components and layouts effectively
▸Implement authentication and authorization patterns
▸Optimize performance with caching and queues
▸Write robust tests and integrate CI/CD

Final Summary

▸Laravel is a modern PHP framework for web applications and APIs.
▸Follows MVC architecture with expressive syntax.
▸Includes Eloquent ORM, Blade templates, queues, events, and CLI tooling.
▸Supports testing, security, and scalable application development.
▸Extensible and widely supported for small projects to enterprise-grade apps.

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

Monetization

▸Develop SaaS platforms
▸Build custom web applications for clients
▸Offer Laravel consulting services
▸Create premium packages or extensions
▸Training and workshops for Laravel developers

Productivity Tips

▸Use Artisan commands for scaffolding
▸Leverage Eloquent relationships for database efficiency
▸Use Blade components and layouts
▸Cache frequently used data
▸Automate testing and CI/CD pipelines

Basic Concepts

▸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
