MongoDBRef::create — Creates a new database reference
This extension that defines this class is deprecated. Instead, the MongoDB extension should be used. There is no equivalent for this class in the new extension.
The concept of database references, and hence this class, has been deprecated.

Пример #1 MongoDBRef::create() example
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);
?>
