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);
}

?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

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

If you would prefer to have the results returned as an associative array, after executing your query you could call $cursor->setTypeMap like this:

$cursor->setTypeMap(['root' => 'array', 'document' => 'array', 'array' => 'array']);
