MongoDB\Driver\ServerApi::V1

Server API version 1.

例

例1 Declare an API version on a manager

<?php

use MongoDB\Driver\Manager;
use MongoDB\Driver\ServerApi;

$v1 = new ServerApi(ServerApi::v1);
$manager = new Manager('mongodb://localhost:27017', [], ['serverApi' => $v1]);

$command = new MongoDB\Driver\Command(['buildInfo' => 1]);

try {
    $cursor = $manager->executeCommand('admin', $command);
} catch(MongoDB\Driver\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

/* The buildInfo command returns a single result document, so we need to access
 * the first result in the cursor. */
$buildInfo = $cursor->toArray()[0];

echo $buildInfo->version, "\n";

?>

上の例の出力は以下となります。

4.9.0-alpha7-49-gb968ca0

例2 Declare a strict API version on a manager

The following example sets the strict flag, which tells the server to reject any command that is not part of the declared API version. This results in an error when running the buildInfo command. 

<?php

use MongoDB\Driver\Manager;
use MongoDB\Driver\ServerApi;

$v1 = new ServerApi(ServerApi::v1, true);
$manager = new Manager('mongodb://localhost:27017', [], ['serverApi' => $v1]);

$command = new MongoDB\Driver\Command(['buildInfo' => 1]);

try {
    $cursor = $manager->executeCommand('admin', $command);
} catch(MongoDB\Driver\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

/* The buildInfo command returns a single result document, so we need to access
 * the first result in the cursor. */
$buildInfo = $cursor->toArray()[0];

echo $buildInfo->version, "\n";

?>

上の例の出力は以下となります。

Provided apiStrict:true, but the command buildInfo is not in API Version 1
