How can PHP session data be shared between member registration and forum registration in a PHPBB forum?
To share PHP session data between member registration and forum registration in a PHPBB forum, you can store the necessary data in session variables during member registration and then retrieve them during forum registration. This can be achieved by setting session variables with the required data when a user registers as a member and then accessing these session variables when the user registers for the forum.
// During member registration
$_SESSION['username'] = $username;
$_SESSION['email'] = $email;
// During forum registration
$username = $_SESSION['username'];
$email = $_SESSION['email'];
