根据域名跳转页面的php代码。

<?php
            switch ($_SERVER['HTTP_HOST'])
            {
            case "www.18l.net":
            Header("Location:/bbs/index.php");
            break;
            case "18l.net":
            Header("Location:/bbs/index.php");
            break;
            case "www.duoler.com":
            Header("Location:/duoler.com/index.htm");
            break;
            case "www.duoler.com":
            Header("Location:/duoler.com/index.htm");
            break;
            default:
            Header("Location:/bbs/index.php");
            }
?>
现在在浏览器地址栏中输入不同的域名,进入不同的网站喽!~：
