You could also use a third party api to do device detection via user agent string. One such service is www.useragentinfo.co. Just sign up and get your api token and below is how you get the device info via PHP:

";
$url = "https://www.useragentinfo.co/api/v1/device/";

$data = array('useragent' => $useragent);

$headers = array();
$headers[] = "Content-type: application/json";
$headers[] = "Authorization: Token " . $token;

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ($status != 200 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}

curl_close($curl);

echo $json_response;
?>

And here is the sample response if the visitor is using an iPhone:

{
  "device_type":"SmartPhone",
  "browser_version":"5.1",
  "os":"iOS",
  "os_version":"5.1",
  "device_brand":"Apple",
  "bot":false,
  "browser":"Mobile Safari",
  "device_model":"iPhone"
}
