The concept of database references, and hence this class, has been deprecated.
db
Database to use.
ref
Reference to fetch.
Returns the document to which the reference refers or NULL if the document
does not exist (the reference is broken).
Exemplo #1 MongoCollection::createDBRef() example
<?php

$person = $people->findOne();
// dereference the address
$address = MongoDBRef::get($people->db, $person['address']);
?>
