MongoDB\Driver\Server::getInfo

(mongodb >=1.0.0)

MongoDB\Driver\Server::getInfo — Returns an array of information describing this server

说明

final public 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.

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.

参数

此函数没有参数。

返回值

Returns an array of information describing this server.

错误／异常

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

范例

示例 #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());

?>

以上例程的输出类似于：
