That said, I think if you just did: foo('var'); and changed the 'a' in foo/bar to $a then you would get what you want... It won't be a reference nor a pointer, but just a global variable, disguised by using $GLOBALS instead of: global $var; as you should do for clarity. YMMV -- Some people have a "gift" link here. Know what I want? I want you to buy a CD from some indie artist. http://cdbaby.com/from/lynch Yeah, I get a buck. So?
