$manager = new MongoDB\Driver\Manager("mongodb://rs1.example.com,rs2.example.com/?replicaSet=myReplicaSet");
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$writeConcern = new MongoDB\Driver\WriteConcern(2, 1);
try {
$manager->executeBulkWrite('db.collection', $bulk, $writeConcern);
} catch(MongoDB\Driver\Exception\BulkWriteException $e) {
var_dump($e->getWriteResult()->getWriteConcernError()->getMessage());
}
