例1 MongoDB\Driver\Exception\BulkWriteCommandException::getWriteErrors() example

    <?php

    $manager = new MongoDB\Driver\Manager;

    $bulk = new MongoDB\Driver\BulkWriteCommand(['ordered' => false]);
    $bulk->deleteMany('db.coll', []);
    $bulk->insertOne('db.coll', ['_id' => 1]);
    $bulk->insertOne('db.coll', ['_id' => 1]);
    $bulk->insertOne('db.coll', ['_id' => 1]);

    try {
        $result = $manager->executeBulkWriteCommand($bulk);
    } catch (MongoDB\Driver\Exception\BulkWriteCommandException $e) {
        var_dump($e->getWriteErrors());
    }

    ?>

        ["code"]=>
        int(11000)
        ["index"]=>
        int(2)
