Dummy hydrator

Simple package for strict initialization object with an array.

Supported PHP 7.1+

Why?

Imagine class like this

class DummyClass  
{

    /** @var int */
    private $foo;

    public function __construct(array $data)
    {
        foreach($data as $key => $value) {
            $this->$key = $value;
        }
    }

    public function getFoo(): int
    {
        return $this->foo;
    }
}

What if it will be initialized with array like this ['foo' => 'example-string']? No error in object consturction and TypeError is returned only if you use getFoo method. Sad, isn't it?

Let's do it better.

Add new interface \Integer\Hydratable to your class. (Will be removed after dropping support for PHP7.1)

Add trait Integer\DummyHydrator and call this trait in __construct.

Full example:

class DummyClass  implements \Integer\Hydratable
{

    use \Integer\DummyHydrator;
    
    /** @var int */
    private $foo;

    public function __construct(array $data)
    {
        $this->hydrate($data, $this);
    }

    public function getFoo(): int
    {
        return $this->foo;
    }
}
