    }

    /* The buildInfo command returns a single result document, so we need to access
    * the first result in the cursor. */

    Приклад #2 Declare a strict API version on a manager

    The following example sets the strict flag, which tells the server to reject any command that is not part of the declared API version. This results in an error when running the buildInfo command.

    <?php

    use MongoDB\Driver\Manager;
    use     MongoDB\Driver\ServerApi;

    $v1 = new ServerApi(ServerApi::v1, true);
    $manager = new Manager('mongodb://localhost:27017', [], ['serverApi' => $v1]);

    $command = new MongoDB\Driver\Command(['buildInfo' => 1]);

    try {
    $cursor = $manager->executeCommand('admin', $command);
    } catch(    MongoDB\Driver\Exception $e) {
    echo     $e->getMessage(), "\n";
    exit;
    }

    /* The buildInfo command returns a single result document, so we need to access
    * the first result in the cursor. */
    $buildInfo = $cursor->toArray()[0];

    echo     $buildInfo->version, "\n";

    ?>

    Provided apiStrict:true, but the command buildInfo is not in API Version 1
