By the way, what happened to that array_defined() or whatever function which was added? Didn't we say it should be nuked? isset() and empty() are enough IMO especially as NULL is used as undefined.
key_exists(), you mean? I didn't put it in, and as far as I know it's still there.
I'd really like to nuke it.

Without commenting on whether it should be nuked or not, there's no way to implement this functionality with isset() and empty(). Neither of these constructs can be used to figure out whether an element exists and is null. Whether or not this should be detectable is a different issue... Zeev
