如何创建用户帐户？单独的文件夹来保存用户数据——PHP
如何将每个用户的“默认照片”保存到网站上？同一张照片可能会在他们在网站上的一些互动中（可能在聊天会话中）使用，并且可能会显示在他们的个人资料页面上。每个用户都有自己的文件夹吗？如果是这样，我怎样才能创建这样的文件夹。该文件夹会保留在 ftp 上吗？还是MySQL？会占用空间吗？到目前为止，无论上传到服务器上的什么照片，都只是存储在一个名为-'uploadportrait.php'的文件夹中。我能从这里走向何方？如果有人能告诉我这的一般原则，那就太好了！先感谢您。
How would I save each user's 'default photo' onto a website? This same photo may be used during some of their interactions on the site(maybe in a chat session), and it may be displayed on their profile page. Will each user have their own folder? If so, how can I create such a folder. Will this folder stay on ftp? Or MySQL? Will it take any space? As of now, whatever photos are uploaded onto the server, are simply stored in a folder that reads--'uploadportrait.php'. Where can I go from this? If someone can tell me the general principles of this, then that would be great! Thank you in advance.

如果只是一张照片，那么为每个用户创建一个文件夹就没有多大意义。如果您已经有一个有效的上传例程，只需将上传文件的文件路径存储在用户数据库中即可。那么您不需要复制图像。
If it is just one photo it doesn't make much sense to create a folder for each user. If you already have a working upload routine, simply store the file path of the uploaded file inside of the user database. You don't need to duplicate the image then.
