How to prevent re-posts and stupid re-post warning message on page refresh [SOLVED]

I've been searching for a way to prevent that STUPID re-post warning
message from showing up when you hit the refresh button on your
browser...

I finally found a good solution that does not require redirection,
extra pages, etc. etc.

Just run the following commands at the end of your post-processing php
file:

foreach ($_POST as $var => $value) {
unset($var);
}

This way you'll never have re-posting issues and you'll get rid of the
stupid warning message! :D
