Example #1 MongoDB\Driver\WriteResult::getUpsertedIds example

<?php

$manager = new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$bulk->update(['x' => 1], ['$set' => ['y' => 3]]);
$bulk->update(['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->update(['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);

var_dump($result->getUpsertedIds());
