Well, if you have track_vars turned on, you can do:
while(list($var_name, $var_value) = each($HTTP_GET_VARS)) {
echo "$var_name: $var_value<BR>";
}
Will return a list like:
name1: value1
name2: value2
The array HTTP_GET_VARS contains all of the variables set through GET (as in page?variable=value&variable=value) or HTTP_POST_VARS contains all of the post variables, and HTTP_COOKIE_VARS contains all of the cookie variables.
Hope that helps!
