It seems that session_unregister(name) unsets all variables with the same name, e.g. this code will kill variable "login", that you might have got from an HTTP form and that you're going to use in your script session_start(); session_unregister("login"); .... echo $login; // You'll see nothing I had to add reset ($HTTP_POST_VARS); while (list ($key, $val) = each ($HTTP_POST_VARS)) { $$key = $val; } to set back the variables I have got from form. -- Editor's Note: session_unregister() does not care if value is session variable or not. i.e. it unregister the variable from session and unset the variable.
