How to keep <form> from re-submitting on page refresh...

[NoNameNoWhere]

I have forms that are handled by PHP scripts in the same file that
generates the page. After the page regenerates with the results of
the form submission, a refresh of the page re-submits the values of
the previous form. Is there a way to reset or clear that form data
to prevent the re-submission of data?

Thanks

Most simple solution is often do the thing you want with the posted data
in it on the receiving page (use PHP sessions if the data has to 'live
longer'), and redirect (with a proper HTTP header, not some javascript or
meta thingy) to another (or possibly the same page). Posts are 'lost' on
redirects, so no data will be resubmitted on refresh, the browser will go
straight to the page you provided.

As this is not really an HTML but PHP related issue (well, at least the
solution is), I've taken the liberty to post this answer to that group,
and set the follow-up to it.
