Doctrine entity object to array

Question

Wants to convert doctrine entiry object to normal array, this is my code so far,

 $demo = $this->doctrine->em->find(\'Entity\\User\',2);


        

Answer 1

I made a recursive function in my Repository a few months ago, it's not perfect (like, if you have a field createdBy and updatedBy, it will only retrieve the value for one user because of a rather simple protection against recursivity with $aClassNamesDone), but it may help:

    public function entityToArray($entity, &$aClassNamesDone=array(), $latestClassName="") {

    $result = array();

    if(is_null($entity)) {
        return $result;
    }

    $className = get_class($entity);

    // init with calling entity
    if(empty($aClassNamesDone)) {
        $aClassNamesDone[] =$className;
    }

    $uow = $this->getEntityManager()->getUnitOfWork();

    $entityPersister = $uow->getEntityPersister($className);
    $classMetadata = $entityPersister->getClassMetadata();

    //DEPENDS ON DOCTRINE VERSION
    //if(strstr($className, 'DoctrineProxies\\__CG__\\')){
    if(strstr($className, 'Proxies\\__CG__\\')){
        $uow->initializeObject($entity);
    }

    foreach ($uow->getOriginalEntityData($entity) as $field => $value) {

        if (isset($classMetadata->associationMappings[$field])) {

            $assoc = $classMetadata->associationMappings[$field];

            if (isset($classMetadata->columnNames[$field])) {
                $columnName = $classMetadata->columnNames[$field];
                $result[$columnName] = $value;
            }

            // to avoid recursivity we can look for the owning side (gives similar results as Query::HYDRATE_ARRAY):
            // elseif($assoc['isOwningSide']) { ...
            // or we can track entities explored and avoid any duplicates (this will however ignore some fields pointing to the same entity class)
            // for example: only one of createdBy, updatedBy will be kept

            else if(!in_array($assoc['targetEntity'], $aClassNamesDone) || $assoc['targetEntity'] == $latestClassName) {

                try {

                    if ($assoc['targetEntity'] != 'Timestamp') {

                        $aClassNamesDone[] = $assoc['targetEntity'];

                        $targetClass = $this->getEntityManager()->getClassMetadata($assoc['targetEntity']);

                        if (($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::MANY_TO_MANY) || ($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::ONE_TO_MANY)) {

                            $getterName = 'get' . ucfirst($assoc['fieldName']);
                            $entityChildren = $entity->$getterName();
                            foreach ($entityChildren as $oneChild) {
                                $result[$assoc['fieldName']][] = $this->getEntityManager()->getRepository($assoc['targetEntity'])->entityToArray($oneChild, $aClassNamesDone, $assoc['targetEntity']);
                            }

                        } else if (($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::ONE_TO_ONE) || ($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::MANY_TO_ONE)) {

                            $getterName = 'get' . ucfirst($assoc['fieldName']);
                            $entityChild = $entity->$getterName();
                            $result[$assoc['fieldName']] = $this->getEntityManager()->getRepository($assoc['targetEntity'])->entityToArray($entityChild, $aClassNamesDone, $assoc['targetEntity']);

                        }
                    }

                } catch (\Exception $e) {
                    //var_dump('No entityToArray for ' . $assoc['targetEntity']);
                    throw ($e);
                }
            }

        }
    }

    return $result;
}

Answer 2

If you alread have the object entity fetched form the database, you could also work with the DoctrineModule\Stdlib\Hydrator\DoctrineObject.

/**
 * Assume your entity for which you want to create an array is in $entityObject.
 * And it is an instance of YourEntity::class.
 */
$tmpObject = new DoctrineObject($this->entityManager, YourEntity::class);
$data = $tmpObject->extract($entityObject);

Now $data will contain your object as array.

P.S. I'm not sure this was possible when the question was asked.
