Let’s take a look and learn.

建议的方式有三种： 
1）如果你租用的php空间允许设置目录的http访问权限，那么设置一下即可。 
2）可以对文件内容进行加密，那么即使被下载，也没有多大的价值。 
3）可以将这些文件的后缀改为.php，即使用php文件存储应用信息，这样的话，访问者就无法通过http访问到 
这些文件的真实内容了，当然这些文件中的内容必须是正确的php语法，而且内容要使用php语法中的隐藏语法 
将信息隐藏起来，例如一个存放帐号信息的文件如下： 
users.php 

<?php 
/* 
:::user1:password1::user2:password2::user3:password3::: 
*/ 
?>
