In a purely theoretical sense stdClass implies any object as it is the base class of all and as such can be used. Having said that I prefer the usage of object as it has a meaning in PHP when talking about types, is thus explicit in meaning 'any' and stdClass semantically might imply a 'real' instance of the stdClass class itself.
