RE: [PHP-GENERAL] mkdir function and permissions HELP!

Ok, here's the skinny... Like in IIS/NT, file permission don't allow an anonymous user to write to any directory on in the filesystem for obvious security reasons. User 'nobody' is the Linux equiv. of user 'anonymous' on NT. With IIS, you'd have to allow the group "World" access to write to a directory for the webserver to write to it. This holds for PHP/Apache. If you don't have access to write to a directory, you can't create anything in it, including directories. There are two solutions to this. First, you can open up the permissions on the parent directory to allow world write access. This isn't a good idea unless nothing sensitive is in there. This is a common practice for the cgi-bin. To do this, you need to telnet or login to the server and use the following command: chmod 777 /path/to/dir The second option is to use something to authenticate the owner of the parent directory like LDAP. This would most likely need to be installed on the server and have PHP/Apache recompiled --with-ldap. Then you could create the directory as the owner of parent directory. I'm sorry if my IIS/NT lingo isn't the best. It's been awhile.
