Please learn how to post properly on Usenet. Avoid Google Groups in favor

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.
