Why can't I rename/copy a file?

[bpierce]

I have a script that uses fwrite to create a file for backup purposes. The script creates the file just fine, with one strange thing that I haven't figured out. The owner and group are both set to '48'.

If, when this script tries to create this backup file (.txt) and another file of the same name is encountered, I want it to rename the file to *.bak. For some reason my script can't rename or copy the file that it created. I get permissions denied every time.

Any idea why the owner/group is '48' or why the script can't rename a file that it created?

Thanks!

Have you tried doing a chown or chgrp on it?

[bpierce]

Yes, I have, and since it's not my own webserver, I'm just a basic user and don't have permission to do so. Even if I could, that doesn't address the issue entirely because I might be able to chown/chgrp the file manually, but I don't want to have ot do that every time my script creates a new file. I even tried using the chown() and chgrp() functions (crossing my fingers), and received permissions denied.

The strange thing is that I tested this all at home on my personal server (OS X Rocks) and it worked just fine. I think the key is that for some reason the script is writing the file as owner 48 and group 48, and I can't figure out why. Is there a way to tell PHP which owner and group to write the file as? (probably not.)

Thanks,
