MongoDB将ObjectId转换为结果中的字符串

Question

If document has fields with value as MongoId object, it will be returned to php something like http://dl.dropbox.com/u/7017985/Screenshots/26.jpg, is there any way how to return it like simple strings and not as MongoId object.

Why I need it ? Because I need to send result to javascript browser side. I have document which has 2-3 fields which is refs to another document, and they keep as ObjectId.

MongoID supports __toString. If you cast it as a string, or call __toString directly, it will convert the value to a string.
