     End the current session and store session data.

    <para>
     Session data is usually stored after your script terminated
     without the need to call <function>session_write_close</function>, but as
     session data is locked to prevent concurrent writes only one
     script may operate on a session at any time. When using framesets
     together with sessions you will experience the frames loading one
     by one due to this locking. You can reduce the time needed to
     load all the frames by ending the session as soon as all changes
     to session variables are done.
