I think it makes sense to have empty() behave the same as isset() (they are brother functions).
empty($a, $b, $c) would return 0 if non are empty and 1 if one of those variables is empty.

Then should the same argument be applied to empty(), too? For the record, I'm perfectly happy with things the way they are. If I need to test the existence of two variables, I'm content doing so (verbosely) with two isset() calls. Admittedly, I don't see anything wrong or dangerous with extending isset() to test multiple variables, but I just hope this doesn't go too far into the syntactic sugar realm. -- Jon Parise (jon@csh.rit.edu) .
