Yes.
If you use only the $_SESSION array to set/get the values of your session
variables, you do not need (and, in some versions of PHP, MUST NOT use)
session_register() or any of its friends.
The proper coding for what you are doing above is:
session_start();
$_SESSION['username'] = $row['username'];
$_SESSION['user_id'] = $row['user_id'];
$_SESSION['access_level'] = $row['access_level'];
and
if (isset($_SESSION['user_id']) )
{
return true;
}
else
{
return false;
}
(or even just
return isset($_SESSION['user_id']);
! ;)
Cheers!
