Please learn how to post properly on Usenet.  Avoid Google Groups in favor 
of a locally installed newsreader application if possible.

The problem here is that you are falsely assuming that “/” refers to the 
document root.  Instead, it refers to the *filesystem* root, where you/the 
Web server SHOULD NOT have write access.  As “uploads” is a directory on the 
same level as upload.php, it is probably easiest for you just to omit the 
leading “/”.  

However, it would be safest to refer to the document root explicitly, like

  $_SERVER['DOCUMENT_ROOT'] . '/uploads/' . $value

(As you can see, it does not make sense to concatenate '/uploads' . '/' when 
you can just write '/uploads/'.)

It also does not make a lot of sense to create a directory for every second 
of upload since epoch, using time().  If you need to group uploads by date 
for quick access, I suggest you use year/month/date instead.  That said, you 
can rather easily filter an array of file information, so unless there is a 
chance that on different times people would upload files with the *same* 
name where they do *not* want to overwrite the old version, you do not need 
that directory structure.

However, in a multi-user application another piece is missing in any case: 
You need a way to differentiate between the files of users or one user could 
overwrite the file of another.  Using time() _cannot_ prevent that from 
happening, because there is the possibility of concurrent access.
