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:

    array(0) {
    }
    array(1) {
      [0]=>
      object(MongoDB\Driver\Server)#3 (10) {
        ["host"]=>
        string(9) "localhost"
        ["port"]=>
        int(27017)
