การตรวจสอบโดเมนว่างด้วย PHP ไม่ใช่เรื่องยากเย็นแต่ประการใดครับ สามารถทำได้ด้วยการตรวจสอบกับ Whois Server โค้ดที่ผมใช้นี้เป็นการตรวจสอบในลักษณะของ Service โดยให้ผลลัพท์ในรูป XML ซึ่งต่องไปออกแบบส่วนนำผลลัพท์ไปใช้งานอีกทีนะครับ
<?php
  // domain.xml.php
   header("content-type: text/xml; charset=UTF-8");
  // รายชื่อนามสกุลที่ใช้งาน
  $dtds['com'] = array('whois.crsnic.net', 'No match for');
  $dtds['net'] = array('whois.crsnic.net', 'No match for');
  $dtds['org'] = array('whois.publicinterestregistry.net', 'NOT FOUND');
  $dtds['info'] = array('whois.afilias.net', 'NOT FOUND');
  $dtds['name'] = array('whois.nic.name', 'No match');
  $dtds['biz'] = array('whois.nic.biz', 'Not found');
  $dtds['cc'] = array('whois.nic.cc', 'No match');
  $dtds['edu'] = array('whois.internic.net', 'No match for');
  $dtds['ac.th'] = array('whois.thnic.net', 'No match for');
  $dtds['co.th'] = array('whois.thnic.net', 'No match for');
  $dtds['go.th'] = array('whois.thnic.net', 'No match for');
  $dtds['in.th'] = array('whois.thnic.net', 'No match for');
  $dtds['mi.th'] = array('whois.thnic.net', 'No match for');
  $dtds['net.th'] = array('whois.thnic.net', 'No match for');
  $dtds['or.th'] = array('whois.thnic.net', 'No match for');
 // ค่าที่ส่งมา
  if (preg_match('/([a-z0-9\-]+).([a-z0-9.]+)/', str_replace(array('http://', 'www.'), '', trim($_GET['domain'])), $match)) {
    $domain = $match[1];
    $tld = $match[2];
   // whois server
    $whois = $dtds[$tld];
    $connection = @fsockopen($whois[0], 43, $errno, $errstr, 10);
    if ($connection) {
      fputs($connection, "$domain.$tld\n");
     // อ่านข้อมูลตอบกลับจาก server
      $response = '';
      $nameserver = array();
      while (!feof($connection)) {
         $line = fgets($connection, 128);
         if (preg_match('/name server\:(.*)[\r\n]?/iu', $line, $match)) {
            $nameserver[] = trim($match[1]);
         }
         $response .= $line;
     }
     fclose($connection);
    // ตรวจสอบข้อมูลตอบกลับ
     if (preg_match("/$whois[1]/uis", $response)) {
        $result = 'unavailable';
     } else {
        $result = 'available';
     }
  }
  // xml data
  echo '<?xml version="1.0" encoding="UTF-8"?>
';
  echo '<whois>';
  echo "<domain>$domain.$tld</domain>";
  echo '<result>'.$result.'</result>';
  echo '<nameserver>'.implode(',', $nameserver).'</nameserver>';
  echo '</whois>';
}
?>

การตรวจสอบโดเมนว่างด้วยโค้ดด้านบนสามารถทำได้ง่ายๆโดยเรียก URL ที่ติดตั้ง เช่น http://www.xxx.com/domain.xml.php?domain=goragod.com ซึ่งตามที่กำหนดไว้จะสามารถตรวจสอบโดเมนนามสกุล .com .net .org .info และ โดเมนนามสกุล .th ซึ่งหากต้องการตรวจสอบนามสกุลอื่นก็สามารถเพิ่มได้ครับ ที่ตัวแปร $dtds
