用php查询域名的注册时间和注册状态

yun

用php查询域名的注册时间和注册状态，想看下面效果图，直接上代码：

效果演示：

1. <?php
   
2. class SearchDomain
   
3. {
   
4. var $domain="";
   
5. function SetDomain($udomain)
   
6. {
   
7. $this->domain = $udomain;
   
8. }
   
9. //
   
10. // 获取whois并分析域名状态
    
11. // ok 未被注册
    
12. // 非空值 过期时间
    
13. // 空值 未知
    
14. //
    
15. function GetInfo()
    
16. {
    
17. /*
    
18. $dinfo = trim($this->GetWhois());
    
19. if($dinfo=="") return "";
    
20. if(eregi("no match",$dinfo)) return "ok";
    
21. //return $rs;
    
22. */
