Are there any MongoDB ORM's in PHP similar to mongoid? -

i mongoid mapper in ruby, http://www.mongodb.org/display/docs/php+libraries,+frameworks,+and+tools lists down many orm/mappers in php mongodb none looks mongoid(at least @ first glance).

is there mongodb orm in php similar mongoid? provides facility embedding, refernces etc?

so think doctrine close you're looking for. recognize php , ruby tend have different syntaxes. things embedding , referencing little different.

also recognize while mongoid (and many others) have great features regarding embedding/reference carry risks. it's easy create structures difficult query or difficult maintain.
