发布时间：2017-07-24 编辑：jiaochengji.com
分享一例php实现的whois信息、域名过期信息等的查询工具代码，有需要的朋友参考下。
本代码修改自网上流传的版本，并做如下修正：
增加了两百多种域名的支持；
修正了过期时间解析错误的BUG，改进了效率；
whois.php的完整代码：
复制代码 代码示例:
<?php
if(!isset($_GET['domain'])){
echo "1.您未指定要查询的域名！<br />";
echo "2.接口使用方法：/whois.php?domain=<FONT color=#ff0000>域名</FONT><br />";
echo "3.<FONT color=#ff0000>域名</FONT>请勿加<FONT color=#ff0000>www.</FONT><br />";
exit;
}
$domain = $_GET['domain'];

注意：
使用时发现上面的whois server返回的并不是统一格式的信息，并且部分whois server无响应。
部分小后缀域名是无法查询的，还需要进一步处理。
例如，.kr返回韩文数据，.fr,.de返回某种协议的格式，而.ru返回了另 一种格式的协议，说明页面是俄文的。
