Bug #61155 [Nab]: session_strat gives error

Edit report at https://bugs.php.net/bug.php?id=61155&edit=1 ID: 61155 User updated by: elcmusic at inter dot net dot il Reported by: elcmusic at inter dot net dot il Summary: session_strat gives error Status: Not a bug Type: Bug Package: Session related Operating System: Server Version: Apache/2.2.11 PHP Version: 5.3.10 Block user comment: N Private report: N New Comment: When I added $_SESSION['form'] = "anything"; before: $_SESSION['product'] = $_SESSION['form']; the warning did not show! so I guess this because I tried to read an undefined variable. Is it or is it not a bug? Thanks!
