There is no way to do this in PHP, short of using PHP classes and your own
functions to create your own object system.

The above example, by the way, is a perfect example of overuse of
private. If you're going to provide a set function anyway, and you are
not going to have any operator over-loading, why are you making it private
in the first place?

PS I assume you meant to write public: in front of set_owner.

Provide a real example of why you really need private:
