IMHO, the first snippet is confusing (the second as well, if $v is not used in the following code). Actually, you don't want to pop the top of the stack, but you want to simply get it without altering the stack at all. Therefore it seems reasonable to use a function called array_top() (or so) which takes its argument by value. -- Christoph M.
