php определить мобильные браузеры

Есть функция в которую попытался вставить определения браузеров с мобильных(пытаюсь определить по слову 'Mobile') устройств... прошу помощи)

Code:

function user_browser($agent) {
	preg_match("/(mobile|Mobile|MSIE|Opera|Firefox|Chrome|Version|Opera Mini|Netscape|Konqueror|SeaMonkey|Camino|Minefield|Iceweasel|K-Meleon|Maxthon)(?:\/| )([0-9.]+)/", $agent, $browser_info); 
        list(,$browser,$version) = $browser_info;

        if ($browser == 'Mobile' || $browser == 'mobile') 
           return $browser;
        
        if (preg_match("/Opera ([0-9.]+)/i", $agent, $opera)) return 'Opera '.$opera[1]; 
        if ($browser == 'MSIE') { 
                preg_match("/(Maxthon|Avant Browser|MyIE2)/i", $agent, $ie); 
                if ($ie) return $ie[1].' based on IE '.$version; 
                return 'IE '.$version;
        }
        if ($browser == 'Firefox') {
                preg_match("/(Flock|Navigator|Epiphany)\/([0-9.]+)/", $agent, $ff);
                if ($ff) return $ff[1].' '.$ff[2];
        }
        if ($browser == 'Opera' && $version == '9.80') return 'Opera '.substr($agent,-5); 
        if ($browser == 'Version') return 'Safari '.$version;
        if (!$browser && strpos($agent, 'Gecko')) return 'Browser based on Gecko';
        return $browser.' '.$version;
}

Для php все значения объединить в массив и сверять UA, ACCEPT.
