Google\Cloud\Datastore\Transaction::updateBatch PHP Method

updateBatch() public method

No service requests are run when this method is called. Use {@see \Google\Cloud\Datastore\Transaction::commit()} to commit changes. Example: $entities[0]['firstName'] = 'Bob'; $entities[1]['firstName'] = 'John'; $transaction->updateBatch($entities); $transaction->commit();
public updateBatch ( array $entities, array $options = [] ) : Transaction
$entities array The entities to update.
$options array [optional] { Configuration Options @type bool $allowOverwrite Entities must be updated as an entire resource. Patch operations are not supported. Because entities can be created manually, or obtained by a lookup or query, it is possible to accidentally overwrite an existing record with a new one when manually creating an entity. To provide additional safety, this flag must be set to `true` in order to update a record when the entity provided was not obtained through a lookup or query. **Defaults to** `false`. }
return Transaction
