I must say, I like the coalesce() idea a lot. It gives more flexibility over ifsetor() which sounds to me like it only handles 1 variable that is or isn't set. coalesce() would handle any number of variables.
Here's something else to consider though: Would anybody be interested in a parameter for ifsetor() or coalesce() that would use !empty() instead of isset() ? If coalesce() would become the function name of choice, you can't drop in a parameter to achieve what I just said, so an alternative function would be better in that case (or maybe it would be better in any case). I know I'd love to see some variant like this. I use empty() a lot more than isset().
