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";
}
 
?>

The above example will output something similar to:

Dazed and Confused
Ma na ma na
Bohemian Rhapsody

In the above example each $songRef looks something like the following:

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