Примери

<?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";
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
4.9.0-alpha7-49-gb968ca0
Example #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";
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
Provided apiStrict:true, but the command buildInfo is not in API Version 1
