in general this is the case. If you must do somethign after all output sent to
the browser you can register one or more shutdown function to process in hide.
But it's not so common.

Tere is no recursion, it's a different thing. You can avoid it with some
so called state variable.
switch ($status){
case 'BUILD_FORM_FIRST':
case 'CHECK_FORM':
case 'SHOW_RESULT':
}

I'm afraid that you didn't reopen the connection in show.php.
you must initialize each variable in each separate page, because each script
is a totally independent program from each other. SESSION can ease your work
but resources such as connection, result sets, cannot be registered in a
session.

No, at the end of the script PHP sends a ROLLBACK automatically to
postgres. So it can rollback the queries in the actual request (page) only.
