You can't just unset a $_POST variable (well, you can, but it won't work
like you want). When your user hits reload on the browser, the browser
will resend the post, setting it again.

You can, for instance, have the submit button go to another page to
process the data, then redirect back to your original page with a
header() call.

You can also set a value in the $_SESSION to indicate the page was
submitted; you just need to ensure you have a way of unsetting it once
they leave that page.

There are other ways - but these are the two I use most often.
