&reftitle.examples;

### Partial result if at least one write is successful

    <?php

    $manager = new MongoDB\Driver\Manager;

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

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

    var_dump($result?->getInsertedCount());

    ?>

&example.outputs;

    int(1)

### No partial result if no writes are successful

    <?php

    $manager = new MongoDB\Driver\Manager;

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

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

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

    var_dump($result?->getInsertedCount());

    ?>
