例1 MongoDB\Driver\Manager::getServers() example

<?php

$manager 
= new MongoDB\Driver\Manager("mongodb://localhost:27017");

/* The driver connects to the database server lazily, so Manager::getServers()
 * may initially return an empty array. */
var_dump($manager->getServers());

$command = new MongoDB\Driver\Command(['ping' => 1]);
$manager->executeCommand('db'$command);

var_dump($manager->getServers());

?>
