PHP KML 生成器

我在执行 KML 生成器的下一步时遇到问题。我有它，所以当您选择日期时，它会将日期发送到生成器，并创建一个 KML，然后下载该 KML。它创建该文件，但下载的文件名为generator.php。它包含我所有的 KML 信息，但这并不是我想要的。因此，我需要一些帮助或教程来将文件转换为 .kml，最好是我选择的要下载的名称。到目前为止，这是我的代码： index.php

I am having having trouble with the next step of my KML generator. I have it so when you choose a date it will send the date to the generator and it will create a KML that will then be downloaded. It creates the file but the file that is downloaded is called generator.php. It has all my KML information in it, but that is not quite what I was wanting. So I need a little help or a tutorial on getting the file to be a .kml with preferably a name of my choosing that that will be downloaded. Here is my code so far:
index.php

    </head>
    <body>
    <form action="generator.php" method="post">
        <script type="text/javascript">DateInput('orderdate', true, 'YYMMDD')</script>
        <input name="submit" type="submit" value="get KML" />
    </form>

    </body>
</html>

generator.php

<?php

查看 PHP 手册中 header：

如果您希望提示用户
保存您正在发送的数据，例如
生成的 PDF 文件，您可以使用
» 提供的 Content-Disposition 标头
推荐的文件名并强制
浏览器显示保存对话框。

<?php // We'll be outputting a PDF
header('Content-type: application/pdf');

// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');
// The PDF source is in original.pdf
readfile('original.pdf'); ?>

Have a look at Example 1 in the PHP manual for header:

If you want the user to be prompted to
save the data you are sending, such as
a generated PDF file, you can use the
» Content-Disposition header to supply
a recommended filename and force the
browser to display the save dialog.

<?php // We'll be outputting a PDF
header('Content-type: application/pdf');

// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');
// The PDF source is in original.pdf
readfile('original.pdf'); ?>
