Yes, that would be the expected effect of putting in a session_commit() at the beginning. > Perhaps I can do it with some other message passing mechanism (e.g. > a temporary > file) instead of the $_SESSION. Yes, that would be a way to go. Another alternative is to re-start the session each time you want to write an updated value into it and then immediately close it again. The cost of opening and closing a session to write a value into it compared to opening and closing a file to write a value into it may be a factor here, but I leave that comparison as an exercise for the reader. Others on the list may, of course, chip in with further options, or have other useful, or at least witty, comments. Cheers!
