Convert a PHP object to an associative array

Question

I\'m integrating an API to my website which works with data stored in objects while my code is written using arrays.

I\'d like a quick-and-dirty function to convert

For your case it was right/beautiful if you would use the "decorator" or "date model transformation" patterns. For example:

Your model

class Car {
    /** @var int */
    private $color;

    /** @var string */
    private $model;

    /** @var string */
    private $type;

    /**
     * @return int
     */
    public function getColor(): int
    {
        return $this->color;
    }

    /**
     * @param int $color
     * @return Car
     */
    public function setColor(int $color): Car
    {
        $this->color = $color;
        return $this;
    }

    /**
     * @return string
     */
    public function getModel(): string
    {
        return $this->model;
    }

    /**
     * @param string $model
     * @return Car
     */
    public function setModel(string $model): Car
    {
        $this->model = $model;

        return $this;
    }

    /**
     * @return string
     */
    public function getType(): string
    {
        return $this->type;
    }

    /**
     * @param string $type
     * @return Car
     */
    public function setType(string $type): Car
    {
        $this->type = $type;

        return $this;
    }
}

Decorator

class CarArrayDecorator
{
    /** @var Car */
    private $car;

    /**
     * CarArrayDecorator constructor.
     * @param Car $car
     */
    public function __construct(Car $car)
    {
        $this->car = $car;
    }

    /**
     * @return array
     */
    public function getArray(): array
    {
        return [
            'color' => $this->car->getColor(),
            'type' => $this->car->getType(),
            'model' => $this->car->getModel(),
        ];
    }
}

Usage

$car = new Car();
$car->setType('type#');
$car->setModel('model#1');
$car->setColor(255);

$carDecorator = new CarArrayDecorator($car);
$carResponseData = $carDecorator->getArray();

So it will be more beautiful and more correct code.
