If $url is an actual URL to the file, with http:// in the front, you almost for sure cannot chmod that... You have to chmod it as a FILE in the file-system. > That confuses me, because who's the user here? Is it just the system > administrator or the application? In Apache with PHP as a Module, it's the User directive in httpd.conf With CGI, it's that same user, unless it's with suExec, then it could be anybody, unless... In IIS, it's probably E_MACHINE_USERNAME user -- but you're on your own for that one. The EASIEST way to find out, however, is <?php phpinfo();?> which will TELL you which user it is. > And if it is just the system administrator, then can't the system > admin change anything he/she wants anyway? What's the point of having > uid and gid's if a program can't change the permissions of a sibling > file? You do *NOT* want your webserver running as sysadmin!!! THAT WOULD BE REALLY BAD!!! And as to what's the point of uid and gid and who can change what, it's so far off-topic here, in general, that I'll just ignore it, except to say that PHP runs as a specific user, and that user can ONLY change the files it is allowed to change, and that is a GOOD THING. > I have tons of references as to what php filesystem functions are > available, but I need a good reference as to what permissions are and > how they actually can be changed in php -- does anyone have one a > good reference OR care to explain? You should be able to Google for a "Linux filesystem permissions how-to" and get what you want here. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
