将以下代码放在入口文件public/index.php目录下面即可实现

//判断是否是手机

function is_mobile()

{

$user_agent = $_SERVER['HTTP_USER_AGENT'];

$mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong",

break;

}

}

return $is_mobile;

}

is_mobile();

if ( is_mobile() ) {

Header("HTTP/1.1 301 Moved Permanently");

define('BIND_MODULE','index');

Header("Location: http://".$_SERVER["HTTP_HOST"].'/index/index/index');

}else{

Header("HTTP/1.1 301 Moved Permanently");

define('BIND_MODULE','admin');

Header("Location: http://".$_SERVER["HTTP_HOST"].'/admin/index/index');

}

这里因为我在Apache里面配置了省略模块名称，所以要加上define()这个函数。

其中BIND_MODULE的作用详情请参见thinkphp官方文档中的入口绑定部分。
