Allow me to save you some pain...
What you are doing *SEEMS* like a Good Idea to most PHP
not-quite-beginners.
It's not a Good Idea, however, because you end up with too many times
where you end up adding some other include file that ends up using
$name as a variable, and suddenly some other seemingly random portion
of your script stops working -- and you usually don't connect the two,
as the code you added to use $name worked "fine" for some time until
you went to use that one FORM that used this value2var() function that
makes $name global...
Only $name as a global is problematic because you've used it elsewhere.
Don't do what you are doing, because it's going to hurt you a lot
eventually.
Leave the stuff in $_POST, and deal with it early on, and put it
explicitly in variables that you want to use for that script.
Trying to generalize this and write a function and having globals all
over the place will only cause you grief long-term.
