To remove a document based on its ID, you need to ensure that you pass the ID as a MongoID object rather than just a string:



<?php

$id = '4b3f272c8ead0eb19d000000';



// will not work:

$collection->remove(array('_id' => $id), true);



// will work:

$collection->remove(array('_id' => new MongoId($id)), true);

?>
