Using PHP classes to navigate distributed whois databases

So how do you make it say something intelligent if the name you query is available?

In the case of .com/.net/.org,
<br>
the $result->regyinfo and $result->rawdata
<br>
arrays will be empty.
<br>
<br>
Keep in mind whois on it's own isn't enough
<br>
to 100% discern if a domain is available
<br>
or not because "on hold" domains can
<br>
be dropped from whois yet be unavailable
<br>
to register for up to 5 days. Also,
<br>
the whois servers can lag behind the root
<br>
servers for up to 2 days. This is why
<br>
the utils.whois class has a simple
<br>
dns_lookup() which returns true if the
<br>
domain has NS rr's defined (and is thus
<br>
in the roots)
<br>
<br>
For other TLD's we'll have to figure it
<br>
out in the extended handlers.
<br>
<br>
<br>

I pretty much had the same problem while developing http://test.simplehq.com/easydots (over 200 countrys supported) to get around this I did it a crude way.

I check for a domain name that was not taking, counted the characters in the message then had a simple loop
if $result != totalnonmessage
{
avalibe
}
else
{
its not
}

This works sweet unless they change the not found message!!

Im currently using the whois2 code and merging it with own system (which handles prices and the like), who know I may even post it one time!!!

Hi

Do you know that Christmas Islands (cx) does not work, you have it supported in you class though.

I cant get it to work with my code either.

Any ideas why not?

Its me again

just noticed a mistake with your mx search you need to update the server to whois.nic.mx, i think you made a typo, we all do!!!

It's fixed now, thanks. (FYI, the original
<br>
list of whois servers was derived from
<br>
Richard J Sexton's multi whois client,
<br>
http://dns.vrx.net/tech/rootzone/)
<br>

the .cx whois server seems to simply "hang"
<br>
when queried and has been doing so for
<br>
weeks at least.
<br>
<br>
I was thinking of adding a "hack" for this
<br>
that would simply not bother and push an
<br>
error onto errstr[] a la "the .cx whois
<br>
server is broken" which could then be
<br>
turned off when it finally gets fixed.
<br>
<br>
Maybe I'll do that now.

Ok after emailing them they say that they do not have a whois gateway running although they plan to have it in the next 2 weeks

I have a list here over about 250 whois servers, If its any use to you it yours

Sure, send it over and I'll merge it
in.

Ok its on its way, Ill also send it you the way I have done it, although itll be like you using a club to go hunting (you have a machine gun at the moment) :)

Hi,

I have just tried running this set of PHP scripts, but came up with an error. The code I tried was straight from the FAQ, which was:


<!-- Code -->
<p><pre><font color=#008000><xmp>
include( "main.whois");
$whois = new Whois("test.com");
$result = $whois->Lookup();

if(empty($result->regyinfo)) {
// available
} else {
// taken
}
</xmp></font></pre><p>
<!-- Code -->


and this came up with the following error:


Fatal error: Call to unsupported or undefined function preg_replace() in netsol.whois on line 36

Error in the FAQ, that should read,
$result["regyinfo"]

hi i am total newbie & still trying to learn php. Can anyone help on how to setup the whois script for use on a website. I tried a few things from the faq & the readme & got nothing.

Thanks in advance

Hi people

I was wondering if anyone knew of a way to make a query a whois gateway and make it return all new domain names (say in last day).

If anyone knows this would be a great help.

Thanks

Chris
