How can the PHP code provided be improved to adhere more closely to object-oriented programming principles?

The PHP code can be improved by encapsulating related properties and methods within a class. This will help organize the code, improve reusability, and adhere more closely to object-oriented programming principles. 

class Car {
    private $make;
    private $model;
    
    public function __construct($make, $model) {
        $this->make = $make;
        $this->model = $model;
    }
    
    public function getMake() {
        return $this->make;
    }
    
    public function getModel() {
        return $this->model;
    }
}

$car = new Car('Toyota', 'Camry');
echo $car->getMake(); // Output: Toyota
echo $car->getModel(); // Output: Camry
