Is there a simple way to have a php page create anew form containing
the full set of POST variables received from submitting the previous
page - without knowing what the names of the fields will be or how
many there will be?

I am developing a page which normally self-submits (ie the form submit
action points to $_SERVER['PHP_SELF']). That is working fine, BUT if
the user has dawdled a long time on the page, I will need to route the
submit via a re-log-in page - without losing the update data that is
held in the form variables. The re-log-in page would then submit its
form data back to the main page as if it had self-referred (with the
difference that the login data at the server will have been refreshed)

I know I could use use php to hard-code each POST variable that the re-
login page will receive - but I rather suspect there is an easier way.

Suggestions, please
