You're right, return is a statement.
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.... Please let me know...
