例如，下面WEB应用可能向登入用户显示敏感信息：

复制代码 代码如下:

$authenticated = FALSE;
$authenticated = check_auth();
if ($authenticated)
{
    include './sensitive.php';
}
?>

由于sensitive.php位于网站主目录下，用浏览器能跳过验证机制直接访问到该文件。这是由于在网站主目录下的所有文件都有一个相应的URL地址。在某些情况下，这些脚本可能执行一个重要的操作，这就增大了风险。
为了防止后门URL，你需要确认把所有包含文件保存在网站主目录以外。所有保存在网站主目录下的文件都是必须要通过URL直接访问的。
