I need to get the domain name of the local machine. I'm running a CLI script in PHP 4.3-cvs (on OpenBSD) so I have no HTTP or other global vars to look at. The posix_uname command doesn't include the domain on non-GNU OSs. I can get the hostname, but not the domain. Can I get it through some other PHP command? I'd really prefer not to resort to rummaging in /etc and parsing files or doing something silly like a DNS lookup... Any ideas?
