I've had a terrible time with PHP permissions myself. Installing and PHP applications like gallery2 always generate a lot of files and directories owned by apache. When I want to uninstall those applications I'm always left with a bunch of junk I don't have permission to delete. Very annoying since I don't have sudo access. The following PHP script solves this by making the directory you specify world-writable so that you can edit or delete the files and directories within. I realize that was not the specific problem of the parent poster, but I thought someone might find this as useful as I have.

Gallery Cleanup Script
</font>
<p>
Because Gallery runs as part of the webserver, any files it creates
are owned by the webserver process. If you want to modify those
files yourself, you need to get the webserver to change the permissions
on them so that you have access. That's what this script is for.
Simply enter the path to your albums directory below and this script
will make every file in that path (that it can access) writable
by everybody. Then, you can do whatever you want to the files.

Path (on your filesystem) to a file or directory to fix?
