注意两点：
1,index.php要include一下whois文件。
2,通过post方式传name = "yuming"这个值来实现查询，index.php传，whois.php接收。
接收方式
1 //接收域名值 2 if ($_SERVER["REQUEST_METHOD"] == "POST"){ 3 $yuming = test_input($_POST["yuming"]); 4 } 5 6 function test_input($data){ 7 $data = trim($data); 8 $data = stripslashes($data); 9 $data = htmlspecialchars($data); 10 return $data; 11 }
