Example #1 MongoDB\Driver\Cursor::getId() example
<?php/* In this example, we insert several documents into the collection and specify * a smaller batchSize to ensure that the first batch contains only a subset of * our results and the cursor remains open on the server. */$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");$query = new MongoDB\Driver\Query([], ['batchSize' => 2]);$bulk = new MongoDB\Driver\BulkWrite;$bulk->insert(['x' => 1]);$bulk->insert(['x' => 2]);$bulk->insert(['x' => 3]);$manager->executeBulkWrite('db.collection', $bulk);$cursor = $manager->executeQuery('db.collection', $query);var_dump($cursor->getId());?>
