// 查询是否存在一个域名  
function SearchDomain($domainName) {  
// 判断域名是否合法,我对正规表达式不熟悉,那位朋友有详细资料,不妨借我一阅 :-)  
// if(!eregi("*.*",$domainName)) {  
// $re[0]="域名只能是字母、数字和“-”(键盘上的减号)组成,且最大长度为26个字符。
请按正确的格式填写域名!";  
// $re[1]="域名名字不符合要求!";  
// return $re;  
// }

if(strpos($name,".cn")) //如果含有国内域名  
$command="whois -h whois.cnnic.net.cn ";  
else  
$command="whois ";  
$query=EscapeShellCmd($command.$name); //防止别人出什么花招  
exec($query,$whoisResult[],$whoisReturnValue);  
for($i=0;$i<count($whoisResult[0]);$i++)  
$result.=$whoisResult[0][$i]."
