Reload/refresh page in browser without re-submitting form?

Question

I have a form on a php page that is submitted to the same page. I noticed that if I reload/refresh the page the form gets re-submitted. How do I code to avoid this in the mo

This assume a lot of things, but maybe is what you are looking for:

if ($_POST)
{
    $success = false;

    /*
     * if all goes OK managing POST data make $success = true;
     * 
     */

    if ($success)
    {
        // this will redirects to your original
        // form's page but using GET method
        // so re-submitting will be no possible
        header("location: {$_SERVER['PHP_SELF']}");
        exit;
    }
}
