How does session hijacking work on a computer?
In both cases, after the user is authenticated on the server, the attacker can take over (hijack) the session by using the same session ID for their own browser session. The server is then fooled into treating the attacker’s connection as the original user’s valid session.
How to delete session regenerate ID in PHP?
Instead of `session_destroy`+`session_start`, use the `$delete_old_session` parameter to `session_regenerate_id` to delete the previous session data. To start a new session and leave the old untouched, simply leave out the argument to `session_regenerate_id`.

Do you need to destroy old session ID?
You should not destroy old session data immediately, but should use destroy time-stamp and control access to old session ID. Otherwise, concurrent access to page may result in inconsistent state, or you may have lost session, or it may cause client (browser) side race condition and may create many session ID needlessly.
