HydratorStrategy extract empty value

[eugene-borovov]

Should we return NULL if the value is empty?

laminas-hydrator/src/Strategy/HydratorStrategy.php

Line 53 in b0edb14

if (! $value instanceof $this->objectClassName) {

This would be a BC break because the behaviour is changed.

I do not want something break )))
I decorated strategy with null check

use Laminas\Hydrator\Strategy\StrategyInterface;

class NullableStrategy implements StrategyInterface
{
    /** @var StrategyInterface */
    private $strategy;

    public function __construct(StrategyInterface $strategy)
    {
        $this->strategy = $strategy;
    }

    public function extract($value, ?object $object = null)
    {
        if ($value === null) {
            return null;
        }

        return $this->strategy->extract($value, $object);
    }

    public function hydrate($value, ?array $data = null)
    {
        if ($value === '' || $value === null) {
            return null;
        }

        return $this->strategy->hydrate($value, $data);
    }
}
