PHP how to reset POST

I try to reset the Post's after I send the form. In some threads I read that it could be $_POST = array(); but when I tried it, it doesn't works.

Are there any solutions to reset the POST's?

<script type="text/javascript">    
  if (window.history.replaceState) {
    // reset form on refresh.
    window.history.replaceState(null, null, window.location.href);
  }
</script>

To reload the page keeping the POST data, use:

window.location.reload();

To reload the page discarding the POST data (perform a GET request), use:

window.location.href = window.location.href;

You can reset the post as follows;

 foreach ($_POST as $key => $value) {
    $_POST[$key] = NULL;
 }

Method 2:-

unset($_POST);

I am currently working on this and came with a working solution.

Just using unset($_POST) is not doing the trick. There is still the popup from to resend the information. The way to reset it is actually to send it to another page. This can be done with the header function.

  header("Location: " . $_SERVER['PHP_SELF']);

You will now be free of the message and your $_POST data.

In order to prevent a form from being re-submitted, you could do something like this - it should be pretty self explanatory:

function uniquePost($posted) {
    // take some form values
    $description = $posted['t_betreff'].$posted['t_bereich'].$posted['t_nachricht']; 
    // check if session hash matches current form hash
    if (isset($_SESSION['form_hash']) && $_SESSION['form_hash'] == md5($description) ) {
       // form was re-submitted return false
       return false;
    }
    // set the session value to prevent re-submit
    $_SESSION['form_hash'] = md5($description);
    return true;
}

if (isset($_POST["t_submit"]) && uniquePost($_POST)) {
    $ticket_query   =   $db->prepare("INSERT INTO `ticket` (`Absender`, `Betreff`, `Abteilung`, `Prioritat`, `Erstellt`, `Nachricht`) VALUES (:sender, :betreff, :abteilung, :priority, :datum, :nachricht)");
    $ticket_query->execute(array(
    'sender'    =>  $_SESSION["id"],
    'betreff'   =>  $t_betreff,
    'abteilung' =>  $t_bereich,
    'priority'  =>  $t_priority,
    'datum'     =>  date('d.m.Y'),
    'nachricht' =>  $t_nachricht                                        
    ));
    // no need to reset the post variables
}
