Beispiel #1 MongoDB\Driver\Manager::executeQuery() example
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$bulk->insert(['x' => 2]);
$bulk->insert(['x' => 3]);
$manager->executeBulkWrite('db.collection', $bulk);
$filter = ['x' => ['$gt' => 1]];
$options = [
'projection' => ['_id' => 0],
'sort' => ['x' => -1],
];
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('db.collection', $query);
foreach ($cursor as $document) {
var_dump($document);
}
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
object(stdClass)#6 (1) {
