No, if you just increase refcount and is_ref is not set, the values will not be referenced to each other (i.e., changing one won't change the other). > > (b) If you don't increase the refcount, the behavior is > > undefined, and is likely to end up crashing PHP. > > Not increasing refcount may actually give > > you the same behavior as setting is_ref to 1, but it would > > crash, sooner or later. > >What I meant was, without setting _either_ refcount or is_ref (so only the >hash_update call), it still works with no mem loss. It's not supposed to work, you may be lucky, but chances are it'd crash. >So, do I need just the refcount++, or the is_ref=1 as well? If you want the values to be connected to each other (changing one will change the other), you need to set is_ref to 1. Otherwise, you don't. In any case, you must update the refcount.
