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;   // global $HTTP_VIA, $HTTP_X_COMING_FROM, $HTTP_COMING_FROM;
