19. MongoId
$doc = $collection->findOne(array(‘_id’ =>
‘4b74ae0d064b35442948da4c’));

20. MongoId
$id = new MongoId(‘4b74ae0d064b35442948da4c’);
$doc = $collection->findOne(array(‘_id’ => $id));

21. MongoId & remove()
Slow(er):
$collection->remove(array(‘key1’ => 5, ‘key2’ => 6));
Fast(er):
$cursor = $collection->find(array(‘key1’ => 5, ‘key2’
=> 6));
$while ($cursor->hasNext())
{
$item = $cursor->getNext();
$key = new MongoId($cursor->key());
$collection->remove(array('_id' => $key));
}
