示例

示例 #1 MongoDB\Driver\BulkWriteCommandResult::getDeleteResults() example

<?php

$manager = new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWriteCommand(['verboseResults' => true]);
$bulk->insertOne('db.coll', ['x' => 1]);
$bulk->updateOne('db.coll', ['x' => 1], ['$set' => ['y' => 3]]);
$bulk->updateOne('db.coll', ['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->updateOne('db.coll', ['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);
$bulk->deleteMany('db.coll', []);

$result = $manager->executeBulkWriteCommand($bulk);

var_dump($result->getDeleteResults()->toPHP());

?>

以上示例的输出类似于：

object(stdClass)#7 (1) {
  ["4"]=>
  object(stdClass)#6 (1) {
    ["deletedCount"]=>
    object(MongoDB\BSON\Int64)#5 (1) {
      ["integer"]=>
      string(1) "3"
    }
  }
}
