PHP DNS记录

Question

当我在一个php脚本中使用dns_get_record来获取域名的DNS记录列表时，会返回一系列记录。

但是如果我再次运行这个脚本，它并不会返回所有相同的结果（即只返回名称服务器），然后再次运行它，它就可以工作了。

以下是我使用的代码：

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

有更好的函数或更可靠的方法来查询DNS记录吗？

不起作用：

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

正常工作：

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

将DNS_ALL添加到函数调用中应该可以解决问题。

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

为确保您收集到所有不同的记录。
