After processing the form data use a header() call to redirect the
browser to the same page. If you hit refresh then, the browser just
sends a normal GET instead of repeating his previous POST request.
This also prevents another thing, which could annoy or confuse visitors:
Assume a normal POST submission without a following redirect. If you now
move on to another page and then go back to the previous one using the
browser's 'back' function, in most browsers an ugly message will pop up,
telling you that the page has expired or that is was the result of a
POST operation and asks if the browser should send the POST data again.
