a word of caution right out of manual:

"
Caution
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use
session_register(), session_is_registered() and session_unregister().
"

another snip from manual:

"
Use of $_SESSION (or $HTTP_SESSION_VARS with PHP 4.0.6 or less) is
recommended for security and code readablity. With $_SESSION or
$HTTP_SESSION_VARS, there is no need to use
session_register()/session_unregister()/session_is_registered() functions.
Users can access session variable like a normal variable.

Hiya

Futher investigation has lead me to some strange results. I checked
phpinfo() and made sure "register global variables is set=on".

I then used:

//In db api
$num_results =mysql_num_rows($db_result);
$_SESSION['num_results'] = $num_results;

//In second file
session_start();
require_once("db_api.php");
echo "THE num_result from db API is ".$_SESSION['num_results'];

This seems to work....

when I try and use register_session() such as:

//In db api
$db_result = mysql_query($querystring);
$num_results =mysql_num_rows($db_result);
session_register("num_results");

//In second file
if (session_is_registered("num_results"))
echo "NUM RESULTS is $num_results";

I dont seem to get a value echoed. Not sure why?

But hopefully $_SESSION will work now...thanks for all your help
Toby and Janet -much appreciated :)
