Question

我在使用KML生成器的下一步时遇到了麻烦。我有它，所以当你选择一个日期时，它会将日期发送到生成器，它将创建一个KML，然后下载。它创建文件，但下载的文件名为generator.php。它包含了我所有的KML信息，但这并不是我想要的。因此，我需要一些帮助或教程，以使文件成为.kml，最好是我选择的名称将被下载。到目前为止，这是我的代码：的index.php

查看header的PHP手册中的示例1：

如果您希望提示用户保存您要发送的数据，例如一个生成的PDF文件，你可以使用 »要提供的Content-Disposition标头建议的文件名并强制执行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'); ?>
