How is this possible?

Hi gang:

I am reviewing some old code (circa 2003) where the programmer had
one script call another and placed variable values in the URL, like
so:



That seems innocent enough. However, in the called script (i.e.,
"user_edit.php") there are no:

$user_id = $_GET['user_id'];
$action = $_GET['action'];

statements to populate the variables, yet the variables get populated
with the values sent!?!

How did he do that?

Incidentally, he did have in the .htaccess file the statement:

php_flag register_globals 1

So I figure that Globals have something to do with it, but I never
use Globals. And if I print_r $GLOBALS, I find that user_id and
action are listed (many times), but I don't see how that works.

Furthermore, something got changed and the entire script no longer
works. So I'm in a quandary to figure this out -- any ideas,
suggestions, references?

Thanks,

tedd
