[quote author="stanleyxu" date="1202580622"] (Is there a "copy-on-write" semantic behind PHP?)[/quote]

Yes. An assignment operator passes by reference until you attempt to modify the data at the other side of that reference, at which point PHP will duplicate the data in memory and make the change on the new copy. I don't think it requires any additional contemplation over Java's "everything's a reference" method, or C's "everything's a value (except pointers)" approach. All three can get you in trouble if you aren't thinking about them clearly.
