Get Host Name with Curl using ip

Is there a way to get the host name using CURL, or what is the preferred w开发者_JS百科ay using PHP?

You don't need to do this in curl. Just use the gethostbyaddr function.

echo gethostbyaddr('1.2.3.4');

My suggestion would be to experiment without using cURL.

Try looking at: gethostbyname(); and gethostbyaddr();

Basicly:

1. Get host IP address by using gethostbyname();
2. Fetch host name by using gethostbyaddr(); with previously fetched IP address.

$ip = gethostbyname('www.example.com');
$host = gethostbyaddr($ip);

echo $host;

Just tested it, and — works, plus, you don't have to know targeted host's IP address.

I don't think you need cURL for this. gethostbyaddr does a reverse DNS lookup. I believe that's what you want.

Could also be gotten with $_SERVER, specifically $_SERVER['HTTP_HOST']
