@AniketSahrawat I get the error: Warning: Cannot modify header information- headers already sent by (output started at..) — mobilcheckneeded, Apr 11 '18 at 09:53
Honestly, I wonder how you managed to clearly know about Google, yet didn't think about using it.. _"How to redirect with PHP"_ and you would get the first result: https://stackoverflow.com/questions/768431/how-to-make-a-redirect-in-php — icecub, Apr 11 '18 at 09:53

"it doesn't work" won't get us anywhere in helping you. How doesn't it work? Does it say the website doesn't exist? Does it tell you the website is only available in the App Store on iOS? Does it not redirect at all? Does it tell you that headers are already sent? Be specific about the problems you're encountering so we can help. — icecub, Apr 11 '18 at 10:02

Try this:

function user_agent(){
    $iPod = strpos($_SERVER['HTTP_USER_AGENT'],"iPod");
    $iPhone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
    $iPad = strpos($_SERVER['HTTP_USER_AGENT'],"iPad");
    $android = strpos($_SERVER['HTTP_USER_AGENT'],"Android");

    function redirect($url){
      if (!headers_sent()){    
        header('Location: '.$url);
        exit;
      } else {  
        echo '<script type="text/javascript">';
        echo 'window.location.href="'.$url.'";';
        echo '</script>';
        echo '<noscript>';
        echo '<meta http-equiv="refresh" content="0;url='.$url.'" />';
        echo '</noscript>'; exit;
      }
   }

   if($iPad||$iPhone||$iPod){
      $url = "http://yoururl.com/ios";
      redirect($url);
   } elseif($android){
      $url = "http://yoururl.com/android";
      redirect($url);
   } else {
      $url = "http://yoururl.com/pc";
      redirect($url);
   }

}
