DNS_GET_RECORD MX查找失敗

我有一個PHP腳本，它使用get_dns_record來檢索並顯示通過表單提交的域的特定DNS記錄。DNS_GET_RECORD MX查找失敗

它工作得很好，除了處理MX記錄的部分有點不可靠。有時候根本沒有顯示MX記錄（在我知道的域名上）。如果刷新2-3次，有時會顯示。有時他們不會。

想法？

function getDNSRecord($domain1) { 
$dns = dns_get_record($domain1, DNS_ANY); 
echo "These are DNS records"; 
foreach($dns as $d) { 
    // Only print A and MX records 
    if($d['type'] != "A" and $d['type'] != "MX") 
     continue; 

    // Print type specific fields 
    switch($d['type']) { 
     case 'A': 
      // Display annoying message 
      echo "<b>\n" . $d['ip'] . "</b>\n is the Primary A Record for this domain."; 
      break; 
     case 'MX': 
      // Resolve IP address of the mail server 
      $mx = dns_get_record($d['target'], DNS_A); 
      foreach($mx as $server) { 
       echo "This MX record for " . $d['host'] . " points to the server <b>\n" . $d['target'] . "</b>\n whose IP address is <b>\n" . $server['ip'] . "</b>. It has a priority of <b>\n" . $d['pri'] . "</b>\n."; 
      } 
     if ($d['target'] == $domain1) { 
      echo "<div id='mx-status'>There is an issue with this MX Record</div>\n"; 
       } else { 
      echo "<div id='mx-status'>This MX Record looks fine.</div>\n"; 
      } 
      break; 
    } 
} 
}

您是否考慮過使用getmxrr()來獲取域的mx記錄？文檔在這裏：http://us2.php.net/manual/en/function.getmxrr.php

是的，但我不知道如何實現它，使用相同的設置。我不僅需要找到MX記錄，還需要顯示它所指向的位置以及目標的IP地址。 – Batfan 2010-08-04 19:58:29
