    if ( $data == "" )
    {
        $data = "\n(0) Records Found!\n";
    }

    header("Content-type: application/octet-stream");

上面的代码用于从MySQL数据库
生成Excel电子表格，但是我们收到以下错误：

The code above is used for generating an Excel spreadsheet from a MySQL database, but we are getting following error:

该文件你试图打开'users.xls'，是一个
不同于文件扩展名指定的格式
验证该文件是否已损坏，并且来自受信任的
源代码打开f ile，你现在要打开文件
吗？

The file you are trying to open, 'users.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?

有什么问题，我们如何解决？ / p>

What is the problem and how do we fix it?

推荐答案

您没有真正生成Excel文件。您正在使用标签作为分隔符生成等于.csv文件。

You're not really generating an Excel file. You're generating what amounts to a .csv file using tabs as the seperator.

要生成真实Excel文件，请使用 PHPExcel 。

To generate a 'real' Excel file, use PHPExcel.
