Example #1 MongoDB\Driver\Command::__construct() example
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$command = new MongoDB\Driver\Command(array("buildinfo" => 1));
try {
    $cursor = $manager->executeCommand("admin", $command);
    $response = $cursor->toArray()[0];
} catch(MongoDB\Driver\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}
var_dump($response);
?>
The above example will output something similar to:
