How to change and entity type in Doctrine2 CTI Inheritance

Question

How (if possible at all) do you change the entity type with Doctrine2, using it\'s Class Table Inheritance?

Let\'s say I have a Person parent class type

Answer 1

PHP doesn't have support for object casting, so Doctrine doesn't support it. To workaround the problem I write this static method into parent classes:

public static function castToMe($obj) {

    $class = get_called_class();
    $newObj = New $class();

    foreach (get_class_vars(get_class($newObj)) as $property => $value) {
        if (method_exists($obj, 'get' . ucfirst($property)) && method_exists($newObj, 'set' . ucfirst($property))) {
            $newObj->{'set' . ucfirst($property)}($obj->{'get' . ucfirst($property)}());
        }
    }

    return $newObj;
}

You can create this method in class Person and use it to cast from Employe to Client and viceversa:

$employe = New Employe();
$client = Client::castToMe($employe);

Now, if you want, you can remove the $employe entity.
