MongoDB\Driver\Server::getInfo
(mongodb >=1.0.0)
MongoDB\Driver\Server::getInfo — Returns an array of information describing this server
説明
Returns an array of information describing the server. This array is derived from the most recent » hello command response obtained through » server monitoring.
注意:
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.

戻り値

例
例1 MongoDB\Driver\Server::getInfo() example
<?php
$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017/');
$rp = new MongoDB\Driver\ReadPreference('primary');
$server = $manager->selectServer($rp);
var_dump($server->getInfo());
?>上の例の出力は、 たとえば以下のようになります。
