If you know the names of the elements in the array you can use them and access the element overwriting it with an empty string

$_POST['item1'] = "" ;

Alternatively you could do it with some sort of loop to access the elements in turn blanking each as you go. this would then work even if you added to the form or removed items from the form.

A way to do this, is to set a session once the form has been process.

Example:

<?php

session_start();

if(!empty($_POST) && !$_SESSION["FORMSUBMITTED"]){ // process the form data only if the session return false

// process your form here

$_SESSION["FORMSUBMITTED"] = true; // set the session to true that the form don't get process again on refresh

}
else if(!empty($_POST) && $_SESSION["FORMSUBMITTED"]){ // if form data his not empty and the session is set ( double post refresh )

$_POST = array(); // empty the form data

}
else if(empty($_POST)){ // if form data is empty reset the session to false

$_SESSION["FORMSUBMITTED"] = false;

}



?>

Hope it could help!
