php文件下载处理

<?php
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=testname.jpg"); 
readfile("images/test.jpg");
 
//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。 
 
<iframe src="1.zip" style="border-style:none;width:0;height:0;"></iframe>
<iframe src="2.zip" style="border-style:none;width:0;height:0;"></iframe>
 
也可以用js生成iframe
*/
?>
Copy after login
