有两种方式实现这个：
1.将下载目录放在文档根目录之外。
并非所有主机都允许这样做，但通常会执行此操作有这样的初始设置
：
\ [根目录]
\public_html
当客户请求时，例如， www.yoursite.com /index.php ，
index.php从public_html目录提供。
根目录仍然无法通过HTTP访问。所以
你可以做的是放置你的下载目录
在\public_html之外：
\ [根目录]
\ public_html
\downloads
然后你的下载脚本可以这样做：
header（''Content-Type：application / zip''）;
readfile（''/ downloads / somefile.zip''）;
2.使用.htaccess文件保护下载目录。
您的下载目录可以位于
文档根目录内，但是您可以通过将.htaccess文件放在包含
以下指令的目录中来禁用对它的HTTP访问
：
订购允许，拒绝
拒绝所有
然后您的下载脚本可以执行以下操作：
header（ ''Content-Type：application / zip''）;
readfile（''downloads / somefile.zip''）;

There are two ways to implement this:
1. Place the downloads directory outside the document root.
Not all hosts allow this, but those that do typically have
an initial setup like this:
\ [Root directory]
\public_html
When a client requests, say, www.yoursite.com/index.php,
the index.php is served from the public_html directory.
The root directory remains inaccessible via HTTP. So
what you can do is to place your downloads directory
outside \public_html:
\ [Root directory]
\public_html
\downloads
Then your download script could do something like this:
header(''Content-Type: application/zip'');
readfile(''/downloads/somefile.zip'');
2. Protect the downloads directory by using an .htaccess file.
Your downloads directory can be located inside the
document root, but you can disable HTTP access to it
by putting an .htaccess file in that directory containing
the following directives:
Order allow,deny
Deny from all
Then your download script could do something like this:
header(''Content-Type: application/zip'');
readfile(''downloads/somefile.zip'');

绝对是。
将文件放在外面的目录中Apache文档根
（这意味着用户永远不能直接浏览网页）。 PHP可以在文件系统的任何地方（允许）访问
文件，而不仅仅是Apache的doc根目录中的目录。
快速和脏/ / somewhere/inside/docroot/download.php脚本：
<？php
Absolutely yes.
Put the files in a directory which is outside the Apache document root
(which means that users can never web browse directly to them). PHP can
access files anywhere on the file system (that it is allowed to), not just
the directories within Apache''s doc root.
Quick and dirty /somewhere/inside/docroot/download.php script:
<?php
filepath =''/ somewhere / outside / docroot /'';
filepath=''/somewhere/outside/docroot/'';
