Example #1 MongoDB\Driver\Command::__construct() example
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$command = new MongoDB\Driver\Command(array("buildinfo" => 1));
try {
$cursor = $manager->executeCommand("admin", $command);
$response = $cursor->toArray()[0];
} catch(MongoDB\Driver\Exception $e) {
echo $e->getMessage(), "\n";
exit;
}
var_dump($response);
?>
The above example will output something similar to:

Commands can accept options as well, as part of the normal structure that you create to send to the server. For example, the maxTimeMS option can be passed with most commands to restrict the amount of time a specific command can run for on the server.
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$command = new MongoDB\Driver\Command(
array(
"distinct" => "beer",
"key" => "beer_name",
"maxTimeMS" => 10,
)
);
try {
$cursor = $manager->executeCommand("beerdb", $command);
$response = $cursor->toArray()[0];
} catch(MongoDB\Driver\Exception\Exception $e) {
echo $e->getMessage(), "\n";
exit;
}
var_dump($response);
?>
