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就会起作用等。
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：
Array（[0] =＆gt; Array（[host] =＆gt; php.net [type] =＆gt; NS [target] =＆gt; remote2.easydns.com [class] =＆gt; IN [ttl] =＆gt; 38772）[1] =＆gt;数组（[host] =＆gt; php.net [type] =＆gt; NS [target] =＆gt; ns1.easydns.com [class] =＆gt; IN [ttl] =＆gt; 38772）[2] =＆gt;数组（[host] =＆gt; php.net [type] =＆gt; NS [target] =＆gt; ns2.easydns.com [class] =＆gt; IN [ttl] =＆gt; 38772）[3] =＆gt;数组（[host] =＆gt; php.net [type] =＆gt; NS [target] =＆gt; remote1.easydns.com [class] =＆gt; IN [ttl] =＆gt; 38772））
WORKING：

将DNS_ALL添加到函数调用应该可以正常工作
$result = dns_get_record("php.net",DNS_ALL);
print_r($result);
确保收集所有不同的记录。
