Examples

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);
}

?>

The above example will output something similar to:

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