Example #1 MongoDB\Driver\WriteResult::getWriteConcernError() example

 <?php

$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());
}

?>

以上例程的输出类似于：

object(MongoDB\Driver\WriteConcernError)#6 (3) {
  ["message"]=>
  string(33) "waiting for replication timed out"
  ["code"]=>
  int(64)
  ["info"]=>
  object(stdClass)#7 (1) {
    ["wtimeout"]=>
    bool(true)
  }
}
