register_global, need some feedback

Hi! With the register_global turned off. I'm working on making the login to work again. So, I have a few questions. 1) $GLOBALS, Where does this come from and where does this goes to? I noticed there is no variable declaration for this, so I just know that it is part of PHP codes, although I haven't figure out what is it part of. 2) What would be the way to go to make it work, when changing it within this script with register_global turned on to turned off? --clip -- while (list($var, $value) = each($GLOBALS[HTTP_POST_VARS]) { $GLOBALS[$var] = stripslashes(trim($value)); } reset ($GLOBALS[HTTP_POST_VARS]); --clip-- I tried different ways to make it work and I kept getting the error saying " Variable passed to each() is not an array or object " " Variable passed to reset() is not an array or object " Thanks FletchSOD
