RE: [PHP] PHP User Permissions

> A running script cannot change its own permissions If you mean can't change it's user ID and/or group ID, that isn't entirely true. If your script is being run as a privileged user on a UNIX system (usually root), you can change the user/group IDs of the process (either effective or real) with the POSIX extension. (posix_seteuid(), posix_setuid(), etc.) I haven't tried it from an Apache process, so I can't say if it will work from a web server (doubtful) but it does work for standalone scripts from the CGI/CLI.
