Namespaces in PHP (Organize Code Like a Framework)

As your project grows, you might have multiple classes named the same: - User - Controller - Logger

Namespaces solve this.

Example

File: `src/Models/User.php`

```php <?php namespace App\Models;

class User { public function __construct(public string $name) {} } ```

File: `index.php`

```php <?php require_once "src/Models/User.php";

use App\Models\User;

$user = new User("Emma Parker"); echo $user->name; ```

Best practice

Use namespaces that match folders: - App\Models - App\Controllers - App\Services

> Next: Autoloading, load classes automatically instead of require everywhere.
