Detect device information like browser name, device name ,device version

Question

I have been looking for a reliable way to have (at least the less obscure ones) :

the name of the browser the version and the platform (OS) it is on maybe more information but the 3 info above are enough.

Answer 1

Not a complete answer but I guess I am pointing in the right direction. You can get all the information about the user's browser and platform in javascript using the code below

   alert(navigator.userAgent);

You will have to create a list of known browsers and platforms, and you will have to compare the userAgent string with them to identify the respective browser/platform.

Answer 2

with php you can get as below :

$user_agent     =   $_SERVER['HTTP_USER_AGENT'];

function getOS() { 

    global $user_agent;

    $os_platform    =   "Unknown OS Platform";

    $os_array       =   array(
                            '/windows nt 6.3/i'     =>  'Windows 8.1',
                            '/windows nt 6.2/i'     =>  'Windows 8',
                            '/windows nt 6.1/i'     =>  'Windows 7',
                            '/windows nt 6.0/i'     =>  'Windows Vista',
                            '/windows nt 5.2/i'     =>  'Windows Server 2003/XP x64',
                            '/windows nt 5.1/i'     =>  'Windows XP',
                            '/windows xp/i'         =>  'Windows XP',
                            '/windows nt 5.0/i'     =>  'Windows 2000',
                            '/windows me/i'         =>  'Windows ME',
                            '/win98/i'              =>  'Windows 98',
                            '/win95/i'              =>  'Windows 95',
                            '/win16/i'              =>  'Windows 3.11',
                            '/macintosh|mac os x/i' =>  'Mac OS X',
                            '/mac_powerpc/i'        =>  'Mac OS 9',
                            '/linux/i'              =>  'Linux',
                            '/ubuntu/i'             =>  'Ubuntu',
                            '/iphone/i'             =>  'iPhone',
                            '/ipod/i'               =>  'iPod',

    foreach ($os_array as $regex => $value) { 

        if (preg_match($regex, $user_agent)) {
            $os_platform    =   $value;
        }

    }   

    return $os_platform;
