使用PHP检索给定域的名称服务器

Question

I am trying to retrieve the name servers of a given domain, preferably in PHP.

I've tried a number of approaches but am unable to get any decent/consistent results and was wondering if anyone knew of a function or class that might help me achieve this?

For example, this whois class has some success, but fails to retireve the name server from dot com TLDs.

I was thinking that I could perhaps use Google's DNS server 8.8.8.8 in some way perhaps, but am unsure how?

Any pointers would be much appreciated.

The answer is this function:

$result = dns_get_record("stackoverflow.com");
var_dump($result);
