MongoDB\Driver\Server::getInfo

PHP function Edit on GitHub ✎

(mongodb >=1.0.0)

Returns an array of information describing this server

Description

MongoDB\Driver\Server::getInfo(): array

Returns an array of information describing the server. This array is derived from the most recent hello command response obtained through server monitoring.

Note

When the driver is connected to a load balancer, this method will return the backing server's hello command response from the initial connection handshake. This is in contrast to other methods (e.g. MongoDB\Driver\Server::getType()), which will return information about the load balancer itself.

Parameters Parameters

Return Values

Returns an array of information describing this server.

Examples

MongoDB\Driver\Server::getInfo() example

php

<?php

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

$rp = new MongoDB\Driver\ReadPreference('primary');
$server = $manager->selectServer($rp);

var_dump($server->getInfo());

?>

The above example will output something similar to:
