This creates a database reference to a document in the addresses collection. The MongoCollection::getName() function returns the name of the collection (not including the database name).
<?php
$addresses = $db->addresses;
$people = $db->people;
// save $address so it has an _id
$addresses->insert($address);
// create a reference
$ref = MongoDBRef::create($addresses->getName(), $address['_id']);
// set the field in $person
$person['address'] = $ref;
$people->save($person);
?>
