I never said, though, to use braces with echo. Actualy I didn't say anything about echo. I never use echo, for some weird reason I just don't like it. I prefer print. So... I don't realy care how echo should be used. But you'll have to admit, using braces makes things a lot easier. And because what this was all about was JavaScript (and not PHP), using braces is a smart thing, because in JavaScript you can make realy ugly constructions in which things _can_ go wrong (no syntax error, but _wrong_) if you don't use braces. In JavaScript it's not required to end each line with a semicolon like in PHP. This can cause weird flows if you also don't use braces. And ehhhh, who said anything about returning multiple values? To be honest... I don't understand what you try to achieve with your post....
