    例1 MongoDB\Driver\Cursor::getId() example

    <?php

    /* In this example, we insert several documents into the collection and specify
    * a smaller batchSize to ensure that the first batch contains only a subset of
    * 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]);
    $manager->executeBulkWrite('db.collection', $bulk);

    $cursor = $manager->executeQuery('db.collection', $query);
    var_dump($cursor->getId());

    ?>

    上の例の出力は、 たとえば以下のようになります。

    object(MongoDB\Driver\CursorId)#5 (1) {
