Get operating system info
PhpOperating SystemUser AgentPhp Problem Overview
I recently started wondering about sites like http://thismachine.info/ that get the user's operating system info. I have not been able to find out how to do that with PHP, and wanted to try to figure it out.
I noticed that they list the user-agent, which gives lots of info about the browser. Do they get the operating system information from that, or from something else? Is there an API I could use to get the user's operating system?
I see how they got the Browser and IP, but could not figure out the Operating System part!

Solution 1 - Php
The code below could explain in its own right, how http://thismachine.info/ is able to show which operating system someone is using.
What it does is that, it sniffs your core operating system model, for example windows nt 5.1 as my own.
It then passes windows nt 5.1/i to Windows XP as the operating system.
Using: '/windows nt 5.1/i' => 'Windows XP', from an array.
You could say guesswork, or an approximation yet nonetheless pretty much bang on.

(Jan. 19/14) There was a suggested edit on Jan. 18, 2014 to add /msie|trident/i by YJSoft a new member on SO.
The comment read as:
Comment: because msie11's ua doesn't include msie (it includes trident instead)
I researched this for a bit, and found a few links explaining the Trident string.

I noticed a question yesterday that could be relevant to this Q&A and may be helpful for some. In regards to:
Mozilla/5.0 (Linux; Android 4.4.2; SAMSUNG-GT-I9505 Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.96 Mobile Safari/537.36

Another edit, and adding a reference link that was asked (and answered/accepted today, Nov. 4/16) which may be of use.
Consult the Q&A here on Stack:
Solution 2 - Php
When you go to a website, your browser sends a request to the web server including a lot of information. This information might look something like this:
GET /questions/18070154/get-operating-system-info-with-php HTTP/1.1
Host: stackoverflow.com
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate,sdch
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Connection: keep-alive
Cookie: <cookie data removed>
Pragma: no-cache
Cache-Control: no-cache
These information are all used by the web server to determine how to handle the request; the preferred language and whether compression is allowed.
In PHP, all this information is stored in the $_SERVER array. To see what you're sending to a web server, create a new PHP file and print out everything from the array.
<pre><?php print_r($_SERVER); ?></pre>
This will give you a nice representation of everything that's being sent to the server, from where you can extract the desired information, e.g. $_SERVER['HTTP_USER_AGENT'] to get the operating system and browser.
Solution 3 - Php
Took the following code from php manual for get_browser.
$browser = get_browser(null, true);
print_r($browser);
The $browser array has platform information included which gives you the specific Operating System in use.
Please make sure to see the "Notes" section in that page. This might be something (thismachine.info) is using if not something already pointed in other answers.
Solution 4 - Php
Based on the answer by Fred-II I wanted to share my take on the getOS function, it avoids globals, merges both lists and detects the architecture (x32/x64)
/**
* @param $user_agent null
* @return string
*/
function getOS($user_agent = null)
{
if(!isset($user_agent) && isset($_SERVER['HTTP_USER_AGENT'])) {
$user_agent = $_SERVER['HTTP_USER_AGENT'];
}

Solution 5 - Php
If you want to get all those information, you might want to read this:
http://php.net/manual/en/function.get-browser.php
You can run the sample code and you'll see how it works:
<?php
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";
$browser = get_browser(null, true);
print_r($browser);
?>
The above example will output something similar to:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3
Array
(
[browser_name_regex] => ^mozilla/5\.0 (windows; .; windows nt 5\.1; .*rv:.*) gecko/.* firefox/0\.9.*$
[browser_name_pattern] => Mozilla/5.0 (Windows; ?; Windows NT 5.1; *rv:*) Gecko/* Firefox/0.9*
[parent] => Firefox 0.9
[platform] => WinXP
[browser] => Firefox

Solution 6 - Php
If you want very few info like a class in your html for common browsers for instance, you could use:
function get_browser()
{
$browser = '';
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if (preg_match('~(?:msie ?|trident.+?; ?rv: ?)(\d+)~', $ua, $matches)) $browser = 'ie ie'.$matches[1];
elseif (preg_match('~(safari|chrome|firefox)~', $ua, $matches)) $browser = $matches[1];
return $browser;
}
which will return 'safari' or 'firefox' or 'chrome', or 'ie ie8', 'ie ie9', 'ie ie10', 'ie ie11'.
Solution 7 - Php
You can look for this information in $_SERVER['HTTP_USER_AGENT'], but its format is free-form, not guaranteed to be sent, and could easily be altered by the user, whether for privacy or other reasons.
If you've not set the browsecap directive, this will return a warning. To make sure it's set, you can retrieve the value using ini_get and see if it's set.
if(ini_get("browscap")) {
$browser = get_browser(null, true);
$browser = get_browser($_SERVER['HTTP_USER_AGENT']);
}
As kba explained in his answer, your browser sends a lot of information to the server while loading a webpage. Most websites use these User-agent information to determine the visitor's operating system, browser and various information.
Solution 8 - Php
If you are in a LAN (Local Area Network) with an Active Directory Domain Controller you can use shell_exec() method to execute commands like:
wmic /node:192.168.1.3 computersystem get /format:List
to get the system information and process the result
