OT: PHP unlink()

As discussed on the PHP.Net site, I am throwing a permission denied error -

Warning: unlink(../images/users/Murray/Creek.jpg) [function.unlink]:
Permission denied in
W:\Webspace\resadmin\madison\madisonconcrete.com\www\manage\m_users_update.php
on line 82

when I try to delete an image file from a folder with this markup -

unlink('../images/users/'.$userName."/".$_POST['images']);

There are several vague workarounds there that I'm not sure I fully
followed. One of them says to make an ftp connection and then use ftp
delete to wipe the file. Is this the best way?

No. Only on the production server.

Yes - that's what has me so tied up in knots....

You could try the PHP-general mailing list. It's frequented by some of
the guys who write the core code for PHP.

Obvious question: did you test the script in your local testing
environment? unlink() definitely works on Windows, but it requires the
correct permissions. Logically speaking, you should be able to delete
items from the same folder that you created them in, but computer logic
doesn't always follow the same rules as human logic.

I don't want to thrash with this. Where do you suggest I go to try to get
an answer?

I have just this one thing I need to do - Delete images that I have
uploaded.

It's the production server, unfortunately.

This is a Windows server. I can upload the file, but I cannot delete it.
Strange....

Not on a Windows server, they're not. Windows uses a different set of
permissions. If you were on a *nix server you might be able to use
umask() to set the permissions of an uploaded image, but I don't know of
any way to do it with Windows and PHP.

this is just an idea, but if the images folder is in your site root you probably do not have the permission to go below that right? "..\\images\"

On a *nix box, you can change permissiosn. Not sure about that W*ndows
box you're using. This is a testing server, right? Is the production
server also Windows, or is it on a *nix box?
