If the code that's doing the rename is running as an Apache module
mod_php, then the process that's doing the rename is likely the Apache
process. It's probably running as nobody or www or apache. It may not
have write permissions to write into the directory where the newfile is
being placed.
To get around this, run php as a CGI script with the CGIwrap wrapper:
http://cgiwrap.sourceforge.net/
This will force the child process running the php code to run as a
specific user ID. It also requires that php be built as a command line
utility.
