session variable in a function

[rolwong]

I've written the following code:

session_start();
include ('myfunction.php');
$language = checkLanguage();

In myfunction.php. Here is the function.
<?
function checkLanguage() {
$language = $HTTP_SESSION_VARS['language'];
....
....
}
?>

When I run the script, error comes up. On the other hand, when I write in this way. Everything is fine
session_start();
$language = $HTTP_SESSION_VARS['language'];

What have I done wrong? thanks for help

It's because $HTTP_SESSION_VARS isn't automatically created inside a function. $_SESSION is, though, and you'll probably have more success using that.

Thanks for your help.
