Is there a way to find out if a file can be chown'd or chgrp'd ? Something like is_writeable() ... Except that you're trying to find out if you can change the Owner or Group of a file.

fileperms() perhaps? http://php.he.net/manual/en/function.fileperms.php You'd have to compare the return value against the uid/gid the webserver runs as, which can be obtained via getmyuid()/getmygid(): http://php.he.net/manual/en/function.getmyuid.php Alternatively, you could check if the file exists, then attempt to chown/chgrp it. If the chown()/chgrp() returns false, you probably don't have permission. steve
