No, this won't work because you're not returning a value. You need to
either have a return statement in this function that says "return $var;"
or you need to use the & sign, which lets you change the value of a
variable outside the namespace of the function. Or scope. I forget
which it is.
Try your above code -- it shouldn't work.
