无法使用PHP创建版本2003的Excel工作表

我正在尝试使用版本 2003 创建 excel 工作表，使用 php 但我没有得到.在我的代码中使用 xlsx 扩展名时，我没有得到 excel 表。我在代码中将版本更改为xls，得到了excel工作表，但无法打开该文件.2003已安装在系统中。任何身体请帮助我..

我在下面给出的代码。

 <?php
 error_reporting(E_ALL ^ E_NOTICE);
 session_start();
//error_reporting(E_ALL);
 ini_set('display_errors', TRUE);
 ini_set('display_startup_errors', TRUE);
 date_default_timezone_set('Europe/London');
