PHP的DNS记录

Question

当我使用dns_get_record一个PHP脚本中得到的一个域的DNS记录列表，返回的记录列表。

不过，如果我运行该脚本再次不返回所有相同的结果（即它只是返回的域名服务器），那么如果我再次运行它，它的工作原理等

这是我的代码使用：

$result = dns_get_record("php.net"); 
print_r($result); 

是否有更好的功能使用或更可靠的查询DNS记录？

不工作：

阵列（[0] =>数组（[主机] => php.net [型] => NS [靶标] => remote2.easydns.com [类] => IN [TTL] => 38772）[1] =>数组（[主机] => php.net [型] => NS [靶标] => ns1.easydns.com [类] => IN [TTL] => 38772 ）[2] =>数组（[主机] => php.net [型] => NS [靶标] => ns2.easydns.com [类] => IN [TTL] => 38772）[3] =>阵列（[主机] => php.net [型] => NS [靶标] => remote1.easydns.com [类] => IN [TTL] => 38772））

WORKING：

Array（[0] => Array（[host] => php.net [type] => M X [pri] => 5 [target] => osu1.php.net [class] => IN [ttl] => 72984）[1] => Array（[host] => php.net [type] => MX [PRI] => 15 [靶标] => smtp.osuosl.org [类] => IN [TTL] => 72984）[2] =>数组（[主机] => php.net [型] => NS [target] => remote2.easydns.com [class] => IN [ttl] => 30054）[3] => Array（[host] => php.net [type] => NS [target] => ns1.easydns.com [class] => IN [ttl] => 30054）[4] => Array（[host] => php.net [type] => NS [target] => ns2.easydns.com [类] => IN [TTL] => 30054）[5] =>数组（[主机] => php.net [型] => NS [靶标] => remote1.easydns.com [类] => IN [ TTL] => 30054））

添加DNS_ALL所述函数调用应该工作

$result = dns_get_record("php.net",DNS_ALL); 
print_r($result); 

要确保你正在收集所有不同的记录。
