using new AUTOGLOBALS

So I wanna learn how to code properly with register_globals off, I reead on PHP.net about the new auto globals and inmy new php4.1.2 windows installation using php.ini-rec edited according to the intall.txt file, and a few changes from books I have (upload tmp dir etc) I'm off to learn how to use the new auto globals. I've tried $_REGISTER and $_POST . Here is what I tried as a simple test. <form method="post" action="somefile.php"> <input type="text" name="is_name"> <input type="submit"> </form> --somefile.php-- <? print("$_REGISTER["is_name"]"); or print("$_POST["is_name"]"); ?> I also tried $HTTP_POST_VARS["name"] I didnt think about it till now but would it work if i assigned say : $is_name = getenv($_POST or $_REGISTER); this came about while I was learning sessions, which were not working right with 4.0 installed with APACHE on windows. So I decided to update my php, as an ISAPI module, instead of running as a cgi version, and I left register_globals off. when I tried to edit an example session script I had from a book to use $_POST, $_REGISTER, or even $_SESSION i got a blank page on the reload. I think sid is returning empty. Can anyone offer me advice on this, proper coding and or proper configuration in PHP.INI I'm trying to learn all this at once-lol, and learn it properly the first time around, especially since register globas will be deprecitated-poof. I WANT TO BE A GOOD PHP DUDE_LOL_HAHA
