说明

final public MongoDB\Driver\Manager::getServers(): array

注意: Since the driver connects to the database lazily, this method may return an empty array if called before executing an operation on the MongoDB\Driver\Manager.

示例

示例 #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());

?>

以上示例的输出类似于：
