$m = new MongoClient();
$cursor = new MongoCommandCursor(
$m, // MongoClient object
'demo.cities', // namespace
[
'aggregate' => 'cities',
'pipeline' => [ [ '$match' => [ '_id' => [ '$exists' => true ] ] ] ],
'cursor' => [ 'batchSize' => 1 ],
]
);
echo "Before iteration started:\n";

echo "\nAfter iteration started:\n";
$cursor->rewind();
var_dump($cursor->info());
