note 27379 deleted from function.empty by sniper

Note Submitter: chris at chaska dot com ---- It does appear to be superfluous -- you're right. I assume you are saying that inside the function, it is impossible for the variable $var to be unset. That certainly makes sense, as that is a common behavior for other languages. I suppose when I wrote the function years ago I was just making sure I did not try to trim() and/or strlen() an unset variable, since it was not clear what PHP would do in such a case. Depending on a few emperical tests doesn't seem safe. I also suppose that if I looked long and hard, I *might* find someplace in some obscure corner of the PHP documentation some note about "local" variables to a function always being set, not unset. Great. I can simplify my function.
