Is there a PHP function or variable giving the local host name?

Question

When a script runs under Apache, I insert $_SERVER['SERVER_NAME'] value into an error reporting e-mail message.

However, if a Web script forks a "worker" job with nohup php ..., $_SERVER['SERVER_NAME'] appears to be empty there. Thus, if an error occurs, it's reported without a host name.

Can I reliably get the host name by means of PHP, without calling Unix hostname command?

Answer 1

php_uname("n")

Answer 2

You can use _GLOBALS['MACHINENAME'] to obtain the information straight from the globals array.
