Example #1 MongoCollection::getDBRef() example

<?php

$playlists = $db->playlists;

$myList = $playlists->findOne(array('username' => 'me'));

// fetch each song in the playlist
foreach ($myList['songlist'] as $songRef) {
    $song = $playlists->getDBRef($songRef);
    echo $song['title'] . "\n";

    Array

        [$ref] => songs
        [$id] => 49902cde5162504500b45c2c
    )
