        <button type="reset" class="action">Reset</button>
       
    </p>
                </form> 

and for Upload.php

<?php

// I used this function during debugging but it serves no purpose at run time for this example

    print_r($array);

    header("Location: insert.php");
    exit;

    exit;

else
