How can I find the hostname of the web server?

I'm trying to find the hostname and IP address of the web server using php.

I found this snippet of code on the web:

<?php
$ip_address = $_SERVER['REMOTE_ADDR'];
$host_name = $_SERVER['REMOTE_HOST'];

echo "<p>ip address = $ip_address</p>";
echo "<p>hostname = $host_name</p>";
?>

but it returns for me.

ip address = 192.168.0.10

hostname =

so whilst it has resolved the IP address correctly, it has failed to
find the hostname at all.

The hostname is in /etc/inet/hosts and '/bin/hostname' returns it OK.
DNS works fine too.

I'm running php 5.0.2, apache 2.52 and Solaris 9 on a Sun.

It is always of the form: month-year@domain. Hitting reply will work
for a couple of months only. Later set it manually. The month is
always written in 3 letters (e.g. Jan, not January etc)

Sorry, I correct myself.

The 192.168.0.10 is the address of the broswer. This is clearly finding
the client rather than the servers data. I want the hostname of the *server*

Is that what you really want? maybe you wnat $_SERVER['HTTP_HOST']
instead?

You were quick !!

No, that returns www.southminster-branch-line.org.uk, where
southminster-branch-line.org.uk is the domain name.

I want it to return "main-webserver" since that is the hostname of the
machine.

I eventually found it myself - calling phpinfo() gave pointers to all of
it.


<?php
$ip_address = $_SERVER["SERVER_ADDR"];
$server_port = $_SERVER['SERVER_PORT'];
$host_name = $_ENV["HOST"];

echo "<p>ip address = $ip_address</p>";
echo "<p>server port = $server_port</p>";
echo "<p>hostname = $host_name</p>";
?>


Returns...


ip address = 192.168.1.15

server port = 80

hostname = main-webserver
