[PHP] Convert array into an extbase object

public function mapProperties(): AnyModel
{
  $properties = [
    'uid' => 123,
    'pid' => 123,
    'firstname' => 'Alex',
    'lastname' => 'Kellner'
    'email' => 'my@email.org'
  ];
  $dataMapper = $this->objectManager->get(TYPO3\CMS\Extbase\Persistence\Generic\Mapper\DataMapper::class);
  $anyModels = $dataMapper->map(AnyModel::class, [$properties]);
  return $anyModels[0];
}


public function mapPropertiesOld(): AnyModel
{
  $properties = [
    'uid' => 123,
    'pid' => 123,
    'firstname' => 'Alex',
    'lastname' => 'Kellner'
    'email' => 'my@email.org'
  ];

  $anyModel = $this->objectManager->get(AnyModel::class);
  $anyModel->setUid($properties['uid');
  $anyModel->setPid($properties['pid');
  $anyModel->setFirstname($properties['firstname');
  $anyModel->setLastname($properties['lastname');
  $anyModel->setEmail($properties['email');
  return $anyModel;
}


public function mapManyRecords(): array
{
  $tableName = 'tx_ext_domain_model_table';
  $queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable($tableName);
  $result = $queryBuilder->select('*')->from($tableName)->setMaxResults(10000)->execute();
  $dataMapper = $this->objectManager->get(DataMapper::class);
  return $dataMapper->map(Table::class, $result->fetchAll());
}

You can also use the PropertyMapper to convert Arrays in Objects, even if the object does not extend AbstractEntity:

$propertyMapper = GeneralUtility::makeInstance(PropertyMapper::class);
$object = $propertyMapper->convert($row, Object::class);
