Doctrine2 export entity to array

Question

I have Product entity with many-to-one to Category entity. I need store Product in session. First of all i try to implement \\Serial

Answer 1

I've had the same problem, i also wanted to have to associated data in the array too. So i came up with the following:

$serializer = new Serializer($this->em); // Pass the EntityManager object
$array = $serializer->serialize($message); // Returns the array (with associations!)

Source:

_em = $em;
    }

    /**
     * Serialize entity to array
     *
     * @param $entityObject
     * @return array
     */
    public function serialize($entityObject)
    {
        $data = array();

        $className = get_class($entityObject);
        $metaData = $this->_em->getClassMetadata($className);

        foreach ($metaData->fieldMappings as $field => $mapping)
        {
            $method = "get" . ucfirst($field);
            $data[$field] = call_user_func(array($entityObject, $method));
        }

        foreach ($metaData->associationMappings as $field => $mapping)
        {
            // Sort of entity object
            $object = $metaData->reflFields[$field]->getValue($entityObject);

            $data[$field] = $this->serialize($object);
        }

        return $data;
    }
}
