推荐答案

直接来自 http://php.net/header

<?php
    // There is contention over if this MIME type is right, but just use it for now.
    header('Content-type: text/javascript');

    header('Content-Disposition: attachment; filename="file.js"');

    readfile('file.js'); // Echo the file
?>

注意:此操作必须在任何其他输出之前完成(并且可能是页面上唯一的事情，除非您希望文件中有其他输出).

NOTE: this must be done before any other output (and can be about the only thing on the page, unless you want other output in your file).
