You can also look at environment variable $QUERY_STRING. For example,
if ($HTTP_SERVER_VARS['QUERY_STRING'] == 'login') {
...do log in procedure
If register_globals is on, all you need is
if ($QUERY_STRING == 'login')
If you might be passing other parameters in the URL, and want to ignore
case, you could use something like:
if (eregi('login', $QUERY_STRING)) {
This would match
www.blah.com?login
www.blah.com?LogIn
www.blah.com?login&user=herman_hollerith
but it would also match
www.blah.com?sloginthemud
www.blah.com?login0
So, a little regular expression twiddling might be in order.
