MongoDB\Driver\WriteResult::getUpsertedIds — Returns an array of identifiers for upserted documents

说明

参数

此函数没有参数。

返回值

Returns an array of identifiers (i.e. "_id" field values) for upserted documents. The array keys will correspond to the index of the write operation (from MongoDB\Driver\BulkWrite) responsible for the upsert.

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

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"
  }
}
