Example #1 MongoDB\Driver\Exception\WriteException::getWriteResult() example

 <?php

$manager = new MongoDB\Driver\Manager('mongodb://localhost');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['_id' => 1]);
$bulk->insert(['_id' => 1]);

try {
    $manager->executeBulkWrite('db.collection', $bulk);
} catch (MongoDB\Driver\Exception\WriteException $e) {
    $writeResult = $e->getWriteResult();

    if ($writeConcernError = $writeResult->getWriteConcernError()) {
        var_dump($writeConcernError);
    }

    if ($writeErrors = $writeResult->getWriteErrors()) {
        var_dump($writeErrors);
    }
}

?>

array(1) {
  [0]=>
  object(MongoDB\Driver\WriteError)#5 (4) {
    ["message"]=>
    string(70) "E11000 duplicate key error index: db.collection.$_id_ dup key: { : 1 }"
    ["code"]=>
    int(11000)
    ["index"]=>
    int(1)
    ["info"]=>
    NULL
  }
}
