If you want to detect clients operating system using PHP then this is the perfect article for you. You can easily detect user browser, IP & operating system from a user when he/she visit your website. We need a function for the detect operating system. This function helps you to detect OS from IP. Our function actually detects OS from user browser. We can get any user browser using $_SERVER['HTTP_USER_AGENT'] variable. Let's see how we create this script. First, we will create a function name as OS() then we will write down some code for this function.

function OS($user_agent){
$exp = explode(" ", $user_agent);
$oses = array (
'Windows 3.11' => 'Win16',
'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)',
'Windows 98' => '(Windows 98)|(Win98)',
'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Vista' => '(Windows NT 6.0)|(Windows Vista)',
'Windows 7' => '(Windows NT 6.1)|(Windows 7)',
'Windows 2003' => '(Windows NT 5.2)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD'=>'OpenBSD',
'Sun OS'=>'SunOS',
'Linux'=>'(Linux)|(X11)',
'Macintosh'=>'(Mac_PowerPC)|(Macintosh)',
'QNX'=>'QNX',
'BeOS'=>'BeOS',
'OS/2'=>'OS/2',
'Palm OS'=>'Palm OS',
'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp/cat)|(msnbot)|(ia_archiver)',
'J2ME-Opera Mini'=>'Opera Mini',
'SonyE'=>'J2ME-MIDP',
'Symbian OS'=>'Symbian OS',
'SymbianOS 6.1'=>'SymbianOS/6.1',
'SymbianOS 7.0'=>'SymbianOS/7.0',
'SymbianOS 8.0'=>'SymbianOS/8.0',
'SymbianOS 9.1'=>'SymbianOS/9.1',
'SymbianOS 9.2'=>'SymbianOS/9.2',
'SymbianOS 9.4'=>'SymbianOS/9.4',
'Mac OS (iPhone)'=>'iPhone',
'Windows CE' => 'Windows CE'
);

foreach($oses as $os=>$pattern){
if (eregi($pattern,$user_agent))
return $os;
}
return 'Unknown OS';
}

we have created the function successfully. Now we will show how this function will work. for executing demo function we will create an index.php file and we will run this function. in index.php we will write down this code.
index.php
<?php
function OS($user_agent){
$exp = explode(" ", $user_agent);
$oses = array (
'Windows 3.11' => 'Win16',
'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)',
'Windows 98' => '(Windows 98)|(Win98)',
'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Vista' => '(Windows NT 6.0)|(Windows Vista)',
'Windows 7' => '(Windows NT 6.1)|(Windows 7)',
'Windows 2003' => '(Windows NT 5.2)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD'=>'OpenBSD',
'Sun OS'=>'SunOS',
'Linux'=>'(Linux)|(X11)',
'Macintosh'=>'(Mac_PowerPC)|(Macintosh)',
'QNX'=>'QNX',
'BeOS'=>'BeOS',
'OS/2'=>'OS/2',
'Palm OS'=>'Palm OS',
'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp/cat)|(msnbot)|(ia_archiver)',
'J2ME-Opera Mini'=>'Opera Mini',
'SonyE'=>'J2ME-MIDP',
'Symbian OS'=>'Symbian OS',
'SymbianOS 6.1'=>'SymbianOS/6.1',
'SymbianOS 7.0'=>'SymbianOS/7.0',
'SymbianOS 8.0'=>'SymbianOS/8.0',
'SymbianOS 9.1'=>'SymbianOS/9.1',
'SymbianOS 9.2'=>'SymbianOS/9.2',
'SymbianOS 9.4'=>'SymbianOS/9.4',
'Mac OS (iPhone)'=>'iPhone',
'Windows CE' => 'Windows CE'
);

foreach($oses as $os=>$pattern){
if (eregi($pattern,$user_agent))
return $os;
}
return 'Unknown OS';
}
echo OS($_SERVER['HTTP_USER_AGENT']);
?>

Now save index.php file and execute this script into a server. then the server will execute your real operating system.
