php dns记录

Question

当我在php脚本中使用dns_get_record获取域的DNS记录列表时，会返回一个记录列表。

但是，如果我再次运行脚本，它不会返回所有相同的结果（即它只返回名称服务器）然后如果我再次运行它，它的工作原理等。

这是我正在使用的代码：

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

是否有更好的使用功能或更可靠的查询DNS记录的方式？

不工作：

数组（[0] =>数组（[主机] => php.net [类型] => NS [目标] => remote2.easydns.com [类] => IN [ttl] => 38772）[1] = > Array（[host] => php.net [type] => NS [target] => ns1.easydns.com [class] => IN [ttl] => 38772）[2] =>数组（[host] => php.net [type] => NS [target] => ns2.easydns.com [class] => IN [ttl] => 38772）[3] =>数组（[host] => php.net [ type] => NS [target] => remote1.easydns.com [class] => IN [ttl] => 38772））

工作方式：

数组（[0] =>数组（[主机] => php.net [类型] => MX [pri] => 5 [目标] => osu1.php.net [class] => IN [ttl] => 72984）[1] =>数组（[host] => php.net [type] => MX [pri] => 15 [target] => smtp.osuosl.org [class] => IN [ttl] => 72984）[2] =>数组（[host] => php.net [type] => 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] =>数组（[host] => php.net [type] => NS [target] => ns2.easydns.com [class] => IN [ttl] => 30054）[5] =>数组（[host] => php.net [ type] => NS [target] => remote1.easydns.com [class] => IN [ttl] => 30054））

将DNS_ALL添加到函数调用应该可行

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

确保您收集所有不同的记录。
