例1 MongoDB\Driver\BulkWriteCommandResult::getUpdateResults() example
<?php
$manager = new MongoDB\Driver\Manager;
$bulk = new MongoDB\Driver\BulkWriteCommand(['verboseResults' => true]);
$bulk->insertOne('db.coll', ['x' => 1]);
$bulk->updateOne('db.coll', ['x' => 1], ['$set' => ['y' => 3]]);
$bulk->updateOne('db.coll', ['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->updateOne('db.coll', ['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);
$bulk->deleteMany('db.coll', []);
$result = $manager->executeBulkWriteCommand($bulk);
var_dump($result->getUpdateResults()->toPHP());
?>上の例の出力は、 たとえば以下のようになります。
