圖靈社群wap版建議

/*
A wap / mobile version (m.ituring.com.cn / wap.ituring.com.cn) of ituring.com.cn  will do us a lot good.
A simplest way of doing that will be using the function below: 
*/

# in PHP
function is_mobile()
{
    $s = $_SERVER['HTTP_USER_AGENT'];
    if(strpos($s, 'Android') or strpos($s, 'iPhone'))
    {
        return true; # link mobile.css # how hard can that be
    }
    else
    {
        return false; # link style.css
    }
}
