Function design recomendation?

I'm about to properly implement cpdf_set_viewer_preferences which is currently just a stub. The underlying function takes a struct with 8 fields. I'd like to avoid having to specify 8 parameters to the PHP equivalent (especially as most of them has sensible defaults). How are structs 'emulated' in other places?
