unserialize($str) must be compatible with Mvc\Model::unserialize($str): void

[pandian1989]

I recently upgrade phalcon 4 to 5.4 under PHP 7.4. When run our existing test cases, we are facing incompatibility issues with respect to unserialize.

Exception:

Fatal error: Declaration of Mockery_11_User::unserialize($string) must be compatible with Phalcon\Mvc\Model::unserialize($serialized): void

Phalcon - 5.4
PHP - 7.4

I tried following code snippet in model

public function serialize(): string
    {
        $data = array(
            'parent' => parent::serialize(),
        );

        return serialize($data);
    }

    public function unserialize($str) : void
    {
        $data = unserialize($str);
        parent::unserialize($data['parent']);
        unset($data['parent']);
        foreach ($data as $key => $value) {
            $this->$key = $value;
        }
    }

Anybody kindly help on this. Thank you

the new version add the dirtyState in the returned json so if you want your test to be compatible with your model you have to upgrade your test as well to mock the dirtyState too.

You can compare both zep source code on both branchs on Mvc/Model.zep
