Example #1 MongoDB\Driver\Cursor::setTypeMap() example

<?php

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$bulk = new MongoDB\Driver\BulkWrite;
$id = $bulk->insert(['x' => 1]);
$manager->executeBulkWrite('db.collection', $bulk);

$query = new MongoDB\Driver\Query(['_id' => $id]);
$cursor = $manager->executeQuery('db.collection', $query);
$cursor->setTypeMap(['root' => 'array']);

foreach ($cursor as $document) {
    var_dump($document);
}

?>

以上例程的输出类似于：

array(2) {
  ["_id"]=>
  object(MongoDB\BSON\ObjectID)#6 (1) {
    ["oid"]=>
    string(24) "56424fb76118fd3267180741"
  }
  ["x"]=>
  int(1)
}
