        'quantity' => 'int',
    ];

    protected $dates = [
        'effectiveDate'
    ];

    public function getEffectiveDateAttribute($date)
    {
        return $date->format($this->getDateFormat());

}

echo $array['name'];
// john smith

$user = new User($array);

echo $user->name; // John Smith
echo $user['name']; // John Smith

Types

Cast variables to other DTOs automatically

class PostData extends DataTransferObject
{
    /** @var string */
    public $title;
    
    /** @var string|null */
    public $body;
    
    /** @var App\DataTransferObjects\Author */
    public $author;
    
    /** @var App\DataTransferObjects\Tag[] */
    public $tags;
}

$postData = new $postData($array);

$postData->author; // Instance of App\DataTransferObjects\Author
$postData->tags; // Array of App\DataTransferObjects\Tag
