How to Cast Objects in PHP

Question

Ive some classes that share some attributes, and i would like to do something like:

$dog = (Dog) $cat;

is it possible or is there any gener

Answer 1

You may think about factories

class XyFactory {
    public function createXyObject ($other) {
        $new = new XyObject($other->someValue);
        // Do other things, that let $new look like $other (except the used class)
        return $new;
    }
}

Otherwise user250120s solution is the only one, which comes close to class casting.
