Just need to find a long time on the internet, to record the

function IsMobile () {$useragent =isset ($_server[' http_user_agent '])? $_server[' Http_user_agent ']: ';    
  $useragent _commentsblock=preg_match (' |\ (. *?\) | ', $useragent, $matches) >0? $matches [0]: '; 
        function Checksubstrs ($substrs, $text) {foreach ($substrs as $substr) if (False!==strpos ($text, $substr)) { 
      return true; 
  return false; $mobile _os_list=array (' Google Wireless transcoder ', ' Windows CE ', ' WindowsCE ', ' Symbian ', ' Android ', ' armv6l ', ' armv5 '
  , ' Mobile ', ' CentOS ', ' mowser ', ' AvantGo ', ' Opera mobi ', ' J2ME/MIDP ', ' Smartphone ', ' go.web ', ' Palm ', ' IPAQ '); $mobile _token_list=array (' PROFILE/MIDP ', ' configuration/cldc-', ' 160x160 ', ' 176x220 ', ' 240x240 ', ' 240x320 ', ' 320x The ', ' up.

   $found _mobile=checksubstrs ($mobile _os_list, $useragent _commentsblock) | |    Checksubstrs ($mobile _token_list, $useragent); 
  if ($found _mobile) {return true; 
  }else{return false; } if (IsMobile ()) {header (' Location:./app/index.php ');//If for mobile, execute jump} else{header (' Location:./web/index.php '); If not on the handset side, perform the Jump}
