All data associated with the current session is destroyed when session destroy() is called. It does not clear any of the session's global variables, nor does it clear the session cookie.
The session file will be deleted with session destroy() (if file storage is used). Otherwise, the session file will remain on the server until it is deleted by garbage collection. So, if you want to ensure that the server's stored session data is erased, you must use session destroy (). This should not be called on every page!
The Abandon method releases the resources of all the objects held in a Session object. If you don't explicitly invoke the Abandon method, the server will remove these objects after the session ends.
