Far as server software goes not really much you can do other than reading the info at phpinfo() . Or you can use

 $_SERVER['SERVER_SOFTWARE']

this will for example, off my webhosting return

Apache/1.3.33 (Unix) mod_gzip/1.3.26.1a mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.9 FrontPage/5.0.2.2635 mod_ssl/2.8.22 OpenSSL/0.9.7a

*linux server generally more descriptive what they are running to PHP.

and on my windows box

Apache/1.3.31 (Win32) PHP/4.3.11-dev

There really isnt a surefire way to know what OS it's running on unless the webserver tells you ( in this case, apache has (unix) and (win32) ), you can more easily tell what your visitors are running by using.

$_SERVER['HTTP_USER_AGENT']

Which in my case returns

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 (ax)

Also its possible to use $_ENV["TERM"] , which on my hosting returns "Linux" but that variables not even aval on the windows box.

But chances are you are the only one that'll need to know your server, and just looking at the results returned by phpinfo() is more than enough.

Hello,

Thanks for the replies. I am using $_SERVER['SERVER_SOFTWARE'] at the moment, just thought I'd ask if there is a better way...

If anyone knows any other way please let me know.

try

<?php
$os = PHP_OS;
echo $os;
?>

Which on linus gives Linux and on XP WINNT (oddly !). No idea what mac or anything else gives you

Hello and sorry for the late reply. I didn't know about the PHP_OS thing, thanks! Looks nice, will test it on different servers and probably be able to use it.

Thanks again!
