PHP Framework Comparison: What are the key differences between Laravel and CodeIgniter?

Laravel and CodeIgniter are popular frameworks in PHP, known for their ease of use (Laravel) and lightweight (CodeIgniter) respectively. The main differences are: 1. Routing system: Laravel uses expression routing, while CodeIgniter uses traditional URI routing. 2. ORM: Laravel uses Eloquent ORM to simplify data processing, while CodeIgniter uses ActiveRecord ORM, which requires more boilerplate code. 3. Models: Laravel models provide CRUD operations, while CodeIgniter models allow greater customizability. 4. Controller: Laravel follows MVC pattern while CodeIgniter uses MHM pattern (where controller is optional).

PHP Framework Comparison: Key Differences between Laravel and CodeIgniter

In PHP development, choosing the right framework is crucial to building efficient, Maintainable web applications are critical. Laravel and CodeIgniter are two of the most popular frameworks today, each with their own pros and cons.

Introduction

Laravel is a full-stack expression-based framework that simplifies development by reducing boilerplate code and providing a powerful toolset. CodeIgniter, on the other hand, is a lightweight framework known for its flexibility, performance, and user-friendly documentation.

Key differences

1. Routing

• Laravel uses an expression routing system that allows You define concise routes.

  Route::get('/hello', function () {
    return 'Hello, world!';
  });

• CodeIgniter uses traditional URI-based routing, although it also provides routing for expressions in CodeIgniter 4.

  $routes->get('hello', 'Welcome::index');

2. ORM

• Laravel’s Eloquent ORM provides object-relational mapping for seamless interaction with the database. Simplify data processing.

  $user = User::find(1);

• CodeIgniter uses the ActiveRecord ORM, which requires more boilerplate code but provides greater flexibility.

  $query = $this->db->get('users');
  $user = $query->row();

3. Model

• Laravel model is a lightweight base class that can provide CRUD operations and other practical methods.

  class User extends Model {
    // ...
  }

• The CodeIgniter model allows greater customizability but requires more boilerplate code.

  class User_model extends CI_Model {
    // ...
  }

4. Controller

• Laravel controller follows the Model-View-Controller (MVC) pattern, separated Business logic and views.

  class UserController extends Controller {
    // ...
  }

• CodeIgniter uses MHM (Model-Helper-Manager) pattern where the controller is optional.

  class Welcome extends CI_Controller {
    // ...
  }

Practical Case

Consider the following example of creating a user:

Laravel

use App\User;

$user = new User;
$user->name = 'John Doe';
$user->email = 'john.doe@example.com';
$user->password = bcrypt('secret');
$user->save();

CodeIgniter

$this->db->insert('users', [
    'name' => 'John Doe',
    'email' => 'john.doe@example.com',
    'password' => password_hash('secret', PASSWORD_DEFAULT)
]);
