To get the server address, you can use $_SERVER['SERVER_ADDR']. However, this only works when your PHP process is running on a webserver, not when running PHP as CLI. Here is a function which will also return the server address when running on linux (eth0 is hardcoded as the network interface, modify if necessary).

<?php

function getServerAddress() {
	if($_SERVER['SERVER_ADDR']) {
		return $_SERVER['SERVER_ADDR'];
	}
	
	$ifconfig = shell_exec('/sbin/ifconfig eth0');
	preg_match('/addr:([\d\.]+)/',$ifconfig,$match);
	
	return $match[1];
}

?>
