You could have a transaction span multiple pages (not scripts), if you keep the
script in memory and use different parts of it with different templates for
different pages. This is possible using FastCGI (http://www.fastcgi.com). I
do this with Perl, occasionally with C, but I did not have spare time to try it
with PHP, although it should work, if you use PHP like a FastCGI CGI script, and
not a one-script-per-page technique.

Of course there are some drawbacks like necessity to always initialise
variables very carefully, possibility of noticeable memory leaks and strange
cacheing effects. In fact with FastCGI you create a persistent server
application connected to your webserver, not just a volatile script.

Regards, Frank.
