是否可以在 PHP scandir 中使用相对路径，身份验证是否会影响 scandir？
我的网站中有一个经过身份验证的目录，其中有一堆照片目录。如果您登录，则可以访问这些照片。
/admin/galleries/
我想在该目录之外构建另一个页面，我可以授予来宾访问权限以查看经过身份验证的目录中的目录列表。
/guest/access/
我只需要 /admin/galleries/ 目录中的目录的简单列表。我正在尝试使用 scandir。
$folderlist = scandir("../../admin/galleries");
这不会返回 false，但会返回空。我不知道为什么？是该目录的身份验证阻止了通过 scandir 的访问吗？我没想到这会影响像 scandir 这样的服务器进程。
是不是相对路径有问题？当我在 /guest/access/ 内创建一个虚拟目录并将 scandir 路径更改为 scandir(".") 时，它会输出该目录的名称。但是，如果我将同一目录移至 /guest/ 目录并将 scandir 更改为 scandir("..") 或 scandir("../. ./guest")，它再次返回空。这让我认为这不是身份验证问题，而是 scandir 本身的问题？
I have an authenticated directory in my site that has a bunch of directories of photos in it. If you log in you can access these photos.
/admin/galleries/
I want to build another page outside of that directory that I can grant guest access to viewing the list of directories in the authenticated directory.
/guest/access/
I just need a simple list of the directories in the /admin/galleries/ dir. I'm trying to use scandir.
$folderlist = scandir("../../admin/galleries");
This doesn't return false, but it returns empty. I'm not sure why? Is it the authentication on that directory that's blocking access via scandir? I wouldn't have thought that would have affected a server process like scandir.
Is the relative path a problem? When I make a dummy directory inside of /guest/access/ and change the scandir path to scandir("."), it outputs that directory's name. But if I move that same directory up into the /guest/ directory and change scandir to scandir("..") or scandir("../../guest"), it returns empty again. That makes me think it's not an authentication problem, but something with scandir itself?

尝试在
/../../之前使用dirname(__FILE__)Try to use
dirname(__FILE__)before your/../../很抱歉这个问题这么长时间没有得到解答：
它没有返回空，我只是没有将正确的相对路径合并到我的 echo 语句中，并通过返回 false 的 is_dir() 语句运行它们，因为这些目录没有存在于本地目录中。愚蠢的错误。
Sorry to have left this question unanswered so long:
It wasn't returning empty, I just hadn't incorporated the correct relative path into my echo statements and had run them through an is_dir() statement that returned false because those directories didn't exist in the local directory. Dumb mistake.
