You can still read/write files with proper permission. (unlink/create files with proper permission also. You can get rid of write permission for directory, too.) Just in case, you didn't know about it :) php.ini entries like safe_mode_opendir_sid safe_mode_opendir_gid will help to improve security still. I just don't need this kind of feature, but others may need it. -- Yasuo Ohgaki _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.comIt happens on our system that there will never be any files owned by user A under a directory owned by user B. But even if there were, I think safe mode should disallow this type of filesystem reading.Under UNIX like systems, /tmp is world writable and everyone on the system can open dir/wirte/read files, but it's possible to secure files/directory under /tmp. I think you can apply the same. GID support also helps to allow opening files certain group. Is it not enough for your security needs?
