PHP implements URL forwarding code
I spent some time researching it and found that it is quite interesting.
Mainly relies on 3 things:
1. $_SERVER["SERVER_NAME"] This variable
2. header("location:http://youname.com"); This function
3. frame This element
The implementation code is as follows:
<?php
//Copyleft - Felix021 的 PHP 转发代码 http://www.felix021.com
$dn=$_SERVER["SERVER_NAME"];
$url=""; //转发地址
$flag=0; //转发方式 0-直接重定向 1-frame隐藏
switch($dn)
{
case "www.felix021.com":
case "felix021.com"
$url="http://www.felix021.com/blog";
$flag=0;
break;
case "blog.felix021.com":
$url="http://www.felix021.com/blog";
$flag=0;
break;
case "wap.felix021.com":
$url="http://www.felix021.com/blog/mobile";
$flag=0;
break;
case "me.felix021.com":
$url="http://localhost";
$flag=0;
break;
case "login.felix021.com":
$url="http://www.felix021.com/login";
$flag=1;
break;
case "eming.felix021.com":
$url="http://eming.whu.edu.cn";
$flag=0;
break;
case "post.felix021.com":
$url="http://post.baidu.com/f?kw=%B7%EB%C3%F4";
$flag=1;
break;
case "tools.felix021.com":
$url="http://www.felix021.com/tools";
$flag=1;
break;
default:
$url="http://www.felix021.com/blog/";
$flag=0;
break;
}
if($flag==0)
{
header("location:".$url);
exit(0);
}
//后面的是隐藏URL转发
?>
