In this system, SFTP will be used to upload large video files to a specific directory on the server. I am writing a PHP script that will be used to copy completely uploaded files to another directory.
My question is, what is a good way to tell if a file is completely uploaded or not? I considered taking note of the file size, sleeping the script for a few seconds, reading the size again, and comparing the two numbers. But this seems very kludgy.
