在网上搜索有两种实现此目的的常用@L_777_4@.
我最喜欢的是在PHP中它的干净？哇. ：D

在PHP中,你可以写

<?PHP

function isIphone($user_agent=NULL) {
    if(!isset($user_agent)) {
        $user_agent = isset($_SERVER['HTTP_USER_AGENT']) ? $_SERVER['HTTP_USER_AGENT'] : '';
    }
    return (strpos($user_agent,'iPhone') !== FALSE);
}

if(isIphone()) {
    header('Location: http://www.yourwebsITe.COM/phone');
    exit();
}

// ...THE REST OF YOUR CODE HERE

?>

并在javascript中可以写

VAR agent = navigator.userAgent;
var isIphone = ((agent.indexOf('iPhone') != -1) || (agent.indexOf('IPOd') != -1)) ;
if (isIphone) {
    window.location.href = 'http://www.yourwebsite.com/phone';
}

希望有帮助.
