    Here's a stackoverflow link showing you how to use this BulkUpdate feature properly and format the updates you add to the class.

    http://stackoverflow.com/questions/24753464/mongo-mass-update-to-lower-case

    eg.
    <?php
    $batch    ->add(
             array(
                     "q" => array( '_id' => $doc['_id'] ),
                     "u" => array(
                         '$set' => array(
                             'UserName' => strtolower($doc['UserName'])
                     )
                 )
             )
         );
    ?>

    Complete example:

    <?php
    $mc     = new MongoClient('localhost');
    $collection = $mc->selectCollection('blog', 'users');

    $update = array(
          'q' => array('foo' => 'bar'),
          'u' => array('$set' => array('foo' => 'baz')),
          'multi' => false,
          'upsert' => false,
    );
    $batch = new MongoUpdateBatch($collection);
    $batch->add((object) $update);
    $batch->execute();
