Close PHP session without saving

I have a php that will be running for a couple minutes. I need to update a variable in the session and continue processing every 20 seconds or so.

This way I can have another script update a screen on the first scripts progress every 20 seconds or so.

I need to close the session without saving, so not to undo any changes that may take place while the script is processing. Then I need to update and save the session to keep the window that the session is open to a minimal.

How do I close an open session without saving it?

Im not completely sure I understand, but if you're just reporting on session data and not setting anything, it shouldn't update anyway unless you specifically set someting in it in this script. Your other script should be able to continue uninterrupted whilst the other one reports on it. Why do you need to 'close' the session, can't you just leave it after reporting?

Closing sessions is done with something like session_destroy() - if you dont call this it should be fine?

In the long script every itterattion I want to update the progress in the session. I know how many loops to need to complete. Each loop takes 10 seconds or so. And if I have 100 loops I know each time I loop I will be 1% done. As the script progresses I want to update this value, so a second script can update the page on progress.

Or you can of course write the data to a database and retrieve it, any method of storing data other than sessions should work I think. a text file with one integer in it will give you the lowest overhead on the server.

I am thinking the text file will be better than:
            session_write_close();
Start Loop
                  session_start();
Save Stuff
            session_write_close();
End Loop

Saving a file seemed to do the trick.
