`<?php
/* In this example, we insert several documents into the collection and specify

* 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]);
