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);
?>
