MongoDB\Driver\Manager::getServers — Return the servers to which this manager is connected

Description

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

Returns an array of MongoDB\Driver\Server instances to which this manager is connected.

Note: 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.

Parameters

This function has no parameters.

Return Values

Returns an array of MongoDB\Driver\Server instances to which this manager is connected.

Errors/Exceptions

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

Examples

Example #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());

?>

The above example will output something similar to:
