header("Content-Type: application/force-download");

header("Content-Disposition: attachment; filename=testname.jpg");

readfile("images/test.jpg");

?>

  分析上述代码:

  第一行代码是强制下载;

  第二行代码是给下载的内容指定一个名字;

  第三行代码是把下载的内容读进文件中。

  一直以为要在一个页面中同时下载多个文件是不可能的,因为php第一次header发送下载信息之后就不能再发送了。

  今天总算知道了一种解决方案,使用iframe来实现。
