That's a horrible syntax, but a fantastic name for a language construct to do the job. Even better might be (something like) first_isset($a, $b, $c) which tells you precisely what's happening: you get the first value that passes the isset() test. I also find the ?? / ??= suggestion very attractive - it would have been my suggestion for a suitable operator. Cheers!
