Maybe I can help :)

Okay... There are easier ways to do this I suspect.

Assuming you have index.php3 and you want index.php3 to pass variables to
mypage.php3... say this:

http://www.mydomain.com/mypage.php3?dog=rover&cat=spot

in mypage.php3.. you can access the as:

echo $dog; // returns "rover"
echo $cat; // returns "spot"

(assuming you have track vars enabled in PHP3 and you are using the GET post
method as above) there is a a array of these values already created:

echo $HTTP_GET_VARS['dog']; // returns "rover"

Now... if you don't have $HTTP_GET_VARS available... at the very top of your
page before you define ANY other variables... do this:

while(list($key, $val) = each($GLOBALS))

        $myqueryarray['$key'] = $val;

Then you'll have the exact same thing as $HTTP_GET_VARS would have... in
fact... if you are switching between GET and POST a lot, you can use the
above method to save confusion.

Hope that helps.
