$manager 
= new MongoDB\Driver\Manager("mongodb://localhost:27017");
$command = new MongoDB\Driver\Command(array("ping" => 1));

}

Notas

Nota:

For write commands, MongoDB\Driver\WriteConcern is included in the command document itself.

Nota:

If a secondary readPreference is used, it is the caller's responsibility to ensure that the command can be executed on a secondary. No validation is done by the driver.
