Question

In my site, i have created functionality to upload MS-Word Document.

and i’m moving that file using following PHP function

move_uploaded_file($_FILES['upload_file']['tmp_name'],$path);

I just want to know What happens if file(word document) is open while uploading it?

does it create any problem or generate any error?

Answer 1

Depends on how Word behaves. If it is in the middle of a write, then you’ll either get a corrupted file or the OS will make the browser wait before uploading it. But this is a rare occurrence.

If the document is open, but Word is not currently writing you will either get an old version of the file, or a semi-saved corrupted state.

Best not risk it, and tell the user to close the file first.
