Bug description:Example #2 for session_regenerate_id is broken in several ways
Description:
------------
Example #2 does carry the caveat that it's "not fully working code,"
however it's not just "not fully working" - it's badly broken, uses
php.ini options incorrectly, and non-functional.
1. The modification of use_strict_mode is wrapping the wrong function.
use_strict_mode restricts calling session_id() with a new value.
Calling session_id() before unlocking use_strict_mode will result in a
logged warning.
2. The example function does _not_ preserve any existing session data,
which session_regenerate_id does. Anyone using the example would lose
all session data for the user.
Before calling session_start(), you need to store the current session
data temporarily in memory, and then restore it afterward.
