Change function to superglobal

[Baldo]

I want to change the code from a ip-function to superglobal.

Is this a right change or did I do something wrong ???

[code]<?
function ip() {
  // global $REMOTE_ADDR;
  // global $HTTP_X_FORWARDED_FOR, $HTTP_X_FORWARDED, $HTTP_FORWARDED_FOR, $HTTP_FORWARDED;
