## Définition d’une classe
```php
class Person {
    private string $name;
    private int $age;

    public function __construct(string $name, int $age) {
        $this->name = $name;
        $this->age = $age;
    }

    public function __toString(): string {
        return 'Name: ' . $this->name . ', Age: ' . $this->age;
