75 *
76 * Note regenerate+destroy should not clear the session data in memory
77 * only delete the session data from persistent storage.
78 *
79 * Care: When regenerating the session ID no locking is involved in PHP's
80 * session design. See https://bugs.php.net/bug.php?id=61470 for a discussion.
81 * So you must make sure the regenerated session is saved BEFORE sending the
82 * headers with the new ID. Symfony's HttpKernel offers a listener for this.
83 * See Symfony\Component\HttpKernel\EventListener\SaveSessionListener.
84 * Otherwise session data could get lost again for concurrent requests with the
85 * new ID. One result could be that you get logged out after just logging in.
86 *
87 * @param bool $destroy Destroy session when regenerating?
88 * @param int $lifetime Sets the cookie lifetime for the session cookie. A null value
89 * will leave the system settings unchanged, 0 sets the cookie
90 * to expire with browser session. Time is in seconds, and is
91 * not a Unix timestamp.
