范例

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

<?php

$manager = new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$bulk->update(['x' => 1], ['$set' => ['y' => 3]]);
$bulk->update(['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->update(['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);
$bulk->delete(['x' => 1]);

$result = $manager->executeBulkWrite('db.collection', $bulk);

var_dump($result->getUpsertedIds());

?>

以上例程的输出类似于：

array(2) {
  [2]=>
  object(MongoDB\BSON\ObjectID)#4 (1) {
    ["oid"]=>
    string(24) "580e62a224f2302f191b880b"
  }
  [3]=>
  object(MongoDB\BSON\ObjectID)#5 (1) {
    ["oid"]=>
    string(24) "580e62a224f2302f191b880c"
  }
}
