How to determine whether the visitor’s device is an iPhone, iPad, or PC

2、php实现

//方法1
$is_iPad = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'iPad');
//方法2
    $agent = strtolower($_SERVER['HTTP_USER_AGENT']);
    $is_pc = (strpos($agent, 'windows nt')) ? true : false;
    $is_iphone = (strpos($agent, 'iphone')) ? true : false;
    $is_ipad = (strpos($agent, 'ipad')) ? true : false;

    if($is_pc){
     echo "PC机";  //by http://bbs.it-home.org
    }
    if($is_iphone){
     echo "iPhone";
    }
    if($is_ipad){
     echo "iPad";
    }
?>

3、htaccess

RewriteCond %{HTTP_USER_AGENT} ^.*iPad.*$
RewriteRule ^(.*)$ http://ipad.jbxue.com [R=301]

如果是 iPad 浏览器，跳转到 iPad 页面。
