示例 #1 MongoDB\Driver\Exception\BulkWriteCommandException::getWriteConcernErrors() example

`<?php
$manager = new MongoDB\Driver\Manager;
$bulk = new MongoDB\Driver\BulkWriteCommand;
$bulk->insertOne('db.coll', ['x' => 1]);
$writeConcern = new MongoDB\Driver\WriteConcern(50);
try {
$result = $manager->executeBulkWriteCommand($bulk, ['writeConcern' => $writeConcern]);
} catch (MongoDB\Driver\Exception\BulkWriteCommandException $e) {
var_dump($e->getWriteConcernErrors());
}
?>`

以上示例的输出类似于：

    array(1) {
      [0]=>
      object(MongoDB\Driver\WriteConcernError)#6 (3) {
        ["message"]=>

        ["code"]=>
        int(100)
        ["info"]=>
        object(stdClass)#8 (1) {
          ["writeConcern"]=>
          object(stdClass)#7 (3) {
            ["w"]=>
            int(50)
            ["wtimeout"]=>
            int(0)
            ["provenance"]=>
            string(14) "clientSupplied"
          }
        }
      }
    }
