很简单的三句话
header('Content-type: application/octet-stream');//输出的类型,下载应用当中没有什么作用
header('Content-Disposition: attachment; filename="马永占.rar"');//下载显示的名字
readfile('myz.rar');//要下的文件,包括路径
就是把服务器上的myz.rar下载,下载显示和保存的名字默认是马永占.rar

附带文档类型及服务器响应类别
一共两个版本.
文档类型   和  服务器响应HTTP的类型
上面的这个可以在上传文件的类型中对应上.下面的差了点.(原文下面的是用来写在文件头上的.来确定该文件是什么类型.)

这种方式在ecshop的商品列表下载中也使用过了，他是先把文件压缩后再通过header方式来下载的
