我找到了解决方案.这是一个转机.而不是像我创建的cookie一样，我使用了会话.有用我想在这里报告代码:

I found a solution. It's a turn-around. instead of the cookie like the one I created, i used the session. it works I would like to report here the code:

session_start();
if (!$_POST) {
   if ((!isset($_SESSION['order_id'])) or $_SESSION['order_id'] != true ){
    $order_id_time = time(); // Assign variables
    $_SESSION['order_id'] = $order_id_time;
    }
$order_id_date = date('l jS \of F Y');
$order_id = $_SESSION['order_id'];
     ...
     ...
     ...
     echo $pag = <<< FORM
     $order_id
     <form action="page.php" method="post">
     ...
     ...
     <input type="submit">
     </form>
FORM;
} elseif  ($_POST) {
    // Read Cookie for Contract
echo $cook = "Order ID: ".$_SESSION["order_id"]."<br /><br />";
     ...
     ...
     ...
session_destroy();
} // End IF ELSEIF
