php 域名转发程序是我从其它地方看到了，通过xml与php交换实现的，下面我们来看看源文件吧。

<?xml version="1.0" encoding="utf-8"?>
<urls>
 <num>1</num>
 <url id="1">
  <domain>test.domain.com</domain>
  <to>http://www.111cn.net/to>
 </url>
</urls>

index.php文件。

<?php
/*
域名伪跳转方案
By IVershuo.cn
*/
 header("content-type:text/html; charset=utf-8");
 $xml = simplexml_load_file("url.xml"); //xml文件路径
 $to = 'http://www.111cn.net'; //默认跳转地址
 foreach ($xml as $key => $value) {
  if($value->domain == $_SERVER['SERVER_NAME']) {
   $to = $value->to;
   break;
  }
 }
 header('Location: '.$to);
?>

 $xmlUrl->addChild('to',$_POST['to']);
 $xml->num[0] = $num;
}

if (@$_GET['del']) {
 removeNode($xml, "//url[@id='".$_GET['del']."']", 'all');
 $xml->num[0] = $num;
}

$sp = fopen($xmlFile,"wb");
fwrite($sp,$xml->asXML());
fclose($sp);
