PHP Frameworks
Modern PHP frameworks accelerate development by providing routing, ORM, templating, and security out of the box. Learn when and how to use them effectively.
1. Laravel Example: Route + Controller + Blade View
Laravel uses an expressive MVC architecture with elegant syntax. Here's how a typical request flows through the framework.
<?php
// routes/web.php - Define application routes
use App\Http\Controllers\ArticleController;
Route::get('/articles', [ArticleController::class, 'index'])->name('articles.index');
Route::get('/articles/{id}', [ArticleController::class, 'show'])->name('articles.show');
Route::post('/articles', [ArticleController::class, 'store'])->middleware('auth');
?><?php
namespace App\Http\Controllers;
use App\Models\Article;
use Illuminate\Http\Request;
class ArticleController extends Controller
{
public function index()
{
$articles = Article::latest()->paginate(10);
return view('articles.index', compact('articles'));
}
public function show(int $id)
{
$article = Article::findOrFail($id);
return view('articles.show', compact('article'));
}
public function store(Request $request)
{
$validated = $request->validate([
'title' => 'required|max:255',
'body' => 'required|min:10',
]);
Article::create($validated);
return redirect()->route('articles.index')->with('success', 'Article created!');
}
}
?>@extends('layouts.app')
@section('content')
<h1>Articles</h1>
@forelse($articles as $article)
<div class="card mb-3">
<div class="card-body">
<h2>{{ $article->title }}</h2>
<p>{{ Str::limit($article->body, 150) }}</p>
<a href="{{ route('articles.show', $article->id) }}">Read More</a>
</div>
</div>
@empty
<p>No articles found.</p>
@endforelse
{{ $articles->links() }}
@endsection2. Symfony Example: Route Annotation + Controller
Symfony uses PHP attributes (annotations) for routing and a structured controller pattern.
<?php
namespace App\Controller;
use App\Entity\Product;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
class ProductController extends AbstractController
{
#[Route('/products', name: 'product_list', methods: ['GET'])]
public function list(EntityManagerInterface $em): Response
{
$products = $em->getRepository(Product::class)->findAll();
return $this->render('product/list.html.twig', [
'products' => $products,
]);
}
#[Route('/products/{id}', name: 'product_show', methods: ['GET'])]
public function show(Product $product): Response
{
// Symfony auto-resolves the entity from the route parameter
return $this->render('product/show.html.twig', [
'product' => $product,
]);
}
}
?>3. Framework Comparison
Choose a framework based on your project size, team expertise, and performance needs.
| Feature | Laravel | Symfony | CodeIgniter | Slim |
|---|---|---|---|---|
| Type | Full-stack | Full-stack | Full-stack (lightweight) | Micro-framework |
| Learning Curve | Moderate | Steep | Easy | Easy |
| ORM | Eloquent | Doctrine | Built-in Query Builder | None (BYO) |
| Templating | Blade | Twig | Native PHP | None (BYO) |
| Best For | Rapid development, startups | Enterprise, complex apps | Small-medium apps | APIs, microservices |
| Community | Very large | Large | Medium | Small |
| PHP Version | 8.1+ | 8.1+ | 7.4+ | 7.4+ |
4. When to Use a Framework vs Plain PHP
Use a Framework When:
- Building a multi-page web application
- You need authentication, sessions, and database ORM
- Working in a team that benefits from conventions
- Security features (CSRF, XSS protection) are critical
- Project will be maintained long-term
Use Plain PHP When:
- Building a simple script or single-page tool
- Performance is critical and overhead must be minimal
- Learning PHP fundamentals (understand the basics first)
- Creating a tiny API with just a few endpoints
- The project has no dependencies and is self-contained
5. Getting Started with Laravel
Set up a new Laravel project in minutes using Composer.
# Install Laravel via Composer
composer create-project laravel/laravel my-app
# Navigate into the project
cd my-app
# Start the development server
php artisan serve
# Create a controller
php artisan make:controller ArticleController --resource
# Create a model with migration
php artisan make:model Article -m
# Run database migrations
php artisan migrate
# Your app is now running at http://localhost:8000Key Takeaways
- Laravel is ideal for rapid development with its elegant syntax, rich ecosystem (Eloquent, Blade, Artisan), and excellent documentation.
- Symfony excels in enterprise applications with its modular component system and strict architecture patterns.
- Choose based on project needs: full-stack frameworks for complex apps, micro-frameworks (Slim) for APIs, plain PHP for simple scripts.
- Learn the fundamentals first — understanding raw PHP makes you more effective with any framework.
- Follow framework conventions (file structure, naming, patterns) to maximize productivity and make code maintainable by other developers.
Best Practice Alert
Start with the framework's official tutorial or starter kit. Learn routing, controllers, and views first before diving into advanced features like queues, events, or service containers. Use the framework's built-in security features (CSRF tokens, query builders, escaping) rather than implementing your own.

Why Learn PHP in 2026?
Despite the rise of Node.js and Python, PHP remains the backbone of web development for compelling reasons:
- Job market demand: Thousands of PHP developer positions available globally. WordPress alone powers 43% of all websites and requires PHP.
- Framework ecosystem: Laravel (the most popular web framework), Symfony, CodeIgniter, and Slim provide professional-grade tooling.
- Low barrier to entry: Shared hosting supports PHP out of the box. No complex server configuration needed to get started.
- PHP 8.x improvements: JIT compiler, named arguments, match expressions, union types, fibers — modern PHP is fast and expressive.
- CMS dominance: WordPress, Drupal, Joomla, Magento, WooCommerce all run on PHP. Knowing PHP gives you access to this entire ecosystem.
- Freelancing opportunities: PHP projects dominate freelance platforms. Many small businesses need WordPress customisation and PHP-based solutions.

How to Get Started with PHP
- Install a local environment — download XAMPP (Windows/Mac/Linux) or Laravel Valet (Mac). This gives you Apache, PHP, and MySQL in one package.
- Create your first file — make a file called
index.phpin your web root and add:<?php echo "Hello, World!"; ?> - Run it in browser — start Apache and visit
http://localhost/index.phpto see output. - Follow this tutorial series — work through each topic in order, running every example on your local setup.
- Build a project — after completing basics through OOP, build a simple CRUD app (todo list, blog, or contact form) to solidify your knowledge.
Frequently Asked Questions
Basic HTML knowledge is helpful since PHP is often embedded in HTML pages. You do not need to be an HTML expert — understanding tags, forms, and page structure is enough to start.
