As a general approach, PHP usually uses void pointers to store any enumerated type (long, pointer, int, etc). There's one exception I can think of, which is the hash, that uses unsigned integers to store the numeric offsets. Resources use hash tables to store themselves, and they usually use the numeric indices. I think it's extremely safe to use 32-bit integers as unique identifiers for 64-bit pointers, by simply casting them. You'd have to be extremely unlucky to bump into a problem because of this data loss. Your chances of winning the lottery are much much bigger. Of course, you mustn't *store* pointers in integers, but that's something different.
