Example #1 MongoDB\Driver\Cursor::getId() example
<?php
/* In this example, we insert several documents into the collection and specify
* a smaller batchSize to ensure that the first batch contains only a subset of
* our results and the cursor remains open on the server. */
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$query = new MongoDB\Driver\Query([], ['batchSize' => 2]);
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$bulk->insert(['x' => 2]);
$bulk->insert(['x' => 3]);
$manager->executeBulkWrite('db.collection', $bulk);
$cursor = $manager->executeQuery('db.collection', $query);
var_dump($cursor->getId(true));
?>Il precedente esempio visualizzerà qualcosa simile a:
object(MongoDB\BSON\Int64)#5 (1) {
["integer"]=>
string(11) "94810124093"
}
