有没有办法检查文件是否使用PHP完全上传？

Question

I have a directory on a remote machine in which my clients are uploading (via different tools and protocols, from WebDav to FTP) files. I also have a PHP script that returns the directory structure. Now, the problem is, if a client uploads a large file, and I make a request during the uploading time, the PHP script will return the file even if it's not completely uploaded. Is there a way to check whether a file is completely uploaded using PHP?

Answer 1

Setup your remote server to move uploaded files to another directory, and only query the directory files are moved to for files.

AFAIK, there is no way (at least cross-machine) to tell if a file is still being uploaded, without doing something like:

1. Query the file's length
2. Wait a few seconds
3. Query the file's length
4. If it's the same, its possibly completed
