When all is said and done, and you simply want to look up pretty wellany domain name in your PHP scripts, you simply need do this:

$whois = new Whois("devshed.com"); $result = $whois->Lookup();
Depending on what we have under the hood as far as extended handlersgo, $result would contain:

In the case of no extended handlers:

will contain an array of the raw output from the whois server.

In the case of a .com/.net/.org domain with *NO* registrar handler:

will contain parse key/value pairs of the registry output, including an array of "nameservers" and

will contain the unparsed raw output from the whois server defined in $result["regyinfo"]["whois"]

....and in the case of a .com/.net/.org/.edu that has a registrar handler you'll have the two as above plus $result["regrinfo"] which will be an array with key/value pairs from the registrar whois server.

To see exactly what we have in our $result or any parts therein wecan use the handy-dandy showObject() function in utils.whois, which is bundled for debugging and diagnostics purposes (along with a coupleof other goodies.)

So, to lookup devshed.com and then examine the actual object we get backwe can do this:

$whois = new Whois("devshed.com"); $result = $whois->Lookup(); include( "utils.whois"); $display = new utils; $display->ShowObject($result);
And the final result is:
A $result["regyinfo"] array with all the registry info, note thatthe nameserver list itself another array in $result["regyinfo"]["nameserver"]:

regyinfo->Array domain->DEVSHED.COM registrar->NETWORK SOLUTIONS, INC. whois->whois.networksolutions.com referrer->www.networksolutions.com nameserver->Array 0->NS1.INFOWEST.COM 1->NS2.INFOWEST.COM
A $result["rawdata"] array that has the raw data from the registrar'swhois server.

rawdata->Array 0->The Data in Network Solutions' WHOIS database is provided by Network 1->Solutions for information purposes, and to assist persons in obtaining 2->information about or related to a domain name registration record. 3->Network Solutions does not guarantee its accuracy. By submitting a 4->WHOIS query, you agree that you will use this Data only for lawful 5->purposes and that, under no circumstances will you use this Data to: 6->(1) allow, enable, or otherwise support the transmission of mass 7->unsolicited, commercial advertising or solicitations via e-mail 8->(spam); or (2) enable high volume, automated, electronic processes 9->that apply to Network Solutions (or its systems). Network Solutions 10->reserves the right to modify these terms at any time. By submitting 11->this query, you agree to abide by this policy. 12-> 13->Registrant: 14->InfoWest Global Internet Services, Inc. (DEVSHED-DOM) 15-> 1845 W. Sunset Blvd. 16-> St. George, UT 84770 17-> US 18-> 19-> Domain Name: DEVSHED.COM 20-> 21-> Administrative Contact: 22-> Cosby, David R (DRC4) dcosby@INFOWEST.COM 23-> 801.674.0165 24-> Technical Contact, Zone Contact: 25-> Gifford, Aaron D (AG44) agifford@INFOWEST.COM 26-> 435-674-0165 (801) 634-9567 (FAX) 435-674-9654 27-> Billing Contact: 28-> InfoWest Domain Services (IDS2-ORG) dns@INFOWEST.COM 29-> 435-674-0165 30->Fax- 435-674-9654 31-> 32-> Record last updated on 06-Aug-1997. 33-> Record created on 06-Aug-1997. 34-> Database last updated on 6-Dec-1999 16:08:49 EST. 35-> 36-> Domain servers in listed order: 37-> 38-> NS1.INFOWEST.COM 39-> NS2.INFOWEST.COM 40->
And finally a $result["regrinfo"] array, because we have a "netsol" handler to parse output from the Network Solutions registrar serverwe have the following data:

regrinfo->Array organization->InfoWest Global Internet Services, Inc. org_handle->DEVSHED-DOM org_address->1845 W. Sunset Blvd. St. George, UT 84770 US domain->DEVSHED.COM admin->Array name-> Cosby, David R handle->DRC4 email->dcosby@INFOWEST.COM tech->Array name-> Gifford, Aaron D handle->AG44 email->agifford@INFOWEST.COM billing->Array name-> InfoWest Domain Services handle->IDS2-ORG email->dns@INFOWEST.COM updated->06-Aug-1997 created->06-Aug-1997 db_updated->6-Dec-1999 16:08:49 EST ns->Array NS1.INFOWEST.COM-> NS2.INFOWEST.COM->
At the time of writing the only extended handler for registrar's is the netsol class. We need further classes for register.com, melbourneIT,COREnic and all the other registrars. Until then, our output would havestopped with the $result["rawdata"] array above.

Another Example:

Looking up something other than a domain name:

$STRING = "MJ177"; require("whois2.php3"); $whois = new Whois(); $whois->Query["server"]="whois.networksolutions.com"; $result = $whois->Lookup($STRING);
$STRING in this case is a Network Solutions contact handle (mine). It could just as easily be a host handle or any other string. The registrarwhois servers at NetSol allow wildcard matching on arbitrary strings.
