Using PHP to get whois data?

I'm looping through rows in my database to get information from whois results.

Here's what I have right now:

function GetEmailFromWhois($domain){    $whois = new Whois();    $query = $domain;    $whois->deep_whois=TRUE;    $result = $whois->Lookup($query, false);    $raw_data = $result["rawdata"];    $email = "";    foreach($raw_data as $item){        $items = explode(":",$item);        if($items[0] == "Registrant Email"){            $email = $items[1];        }    }    return $email;}

The code above gets the Registrant Email from the whois results.

I reference it later on in my code like this: $email = GetEmailFromWhois($domain);

However, at the same time as getting the registrant email, I'd also like to get the Registrant Name, Registrant Phone, and Registrant Country.

I could just copy the code above 3 more times for each of those additional fields, but that would cause there to be 4 whois queries for each domain - instead of just one.

Anyone know how I can get the info I need in a single query and then use it later on in my code?
