First of all, reading another user's session data is a horrible idea. If you need to have shared access to that data - don't store it in the session.
Secondly, reading another doing it via session_start() with the same session ID is an even worse idea - that way you are effectively acting as that user. There's no easy/reliable way to read session data without intercepting it, but that's not by accident, it's exactly because you shouldn't do it.
That being said, don't call session_destroy() and the user's data won't be removed ... destroy means destroy. If you're looking for a way to just close a session, that's session_write_close().
