Q & A's
|
|
|
|
1.0 How do I tell if a domain is available or not?
|
|
|
|
The big difference between this and version 1 is the absence of the
|
|
FOUND flag.
|
|
|
|
Anyways, for .com/.net/.org you can tell that a domain is available
|
|
or not if the regyinfo array is empty.
|
|
|
|
$whois = new Whois("test.com");
|
|
$result = $whois->Lookup();
|
|
|
|
if(empty($result["regyinfo"])) {
|
|
// available
|
|
} else {
|
|
// taken
|
|
}
|
|
|
|
Keep in mind that this isn't 100% surefire. A domain can be dropped from
|
|
the registry for nonpayment, and remain in limbo for up to 5 days where
|
|
it still cannot be registered. Also, whois servers can lag behind the root
|
|
servers by as much as 24 or even 48 hours in extreme cases.
|
|
|
|
You can also check if there are any nameserver RR's defined (and thus infer
|
|
that the domain is in the root servers) by calling ns_rr_defined($domain)
|
|
in the utils extended class.
|
|
|
|
For other TLD's it's up to you to either grep the results for what you know
|
|
to be a "not found" string, or write an extended handler that does a cleaner
|
|
job of it, which you can then submit to this project and immortalize yourself :)
|
|
|
|
|
|
1.1 I'm getting "Fatal error: Call to unsupported or undefined function
|
|
preg_replace()" why?
|
|
|
|
All that means is that the version of PHP you're using doesn't have
|
|
the perl regular expression module. You can either upgrade or in
|
|
the meantime just move netsol.whois out of the php_include_path,
|
|
you won't get nicely parsed output for netsol domains but you
|
|
will still at least get the raw output then.
|
|
|
|
1.2 whois2 breaks under PHP4, I get $result["rawdata"] = Array now instead
|
|
of the actual data!
|
|
|
|
Have look at the returned object using the showObject() function in the
|
|
utils.whois class. Odds are the data will be in $result["rawdata"]["rawdata"]
|
|
instead.
|
|
|
|
This is of course, a bug. I have tried to fix and unsuccessfully, but I
|
|
haven't had too much time either. I think it's some kind of scoping issue
|
|
with classes under PHP4.
|
|
|
|
[This is also fixed as of v2.3 thanks to all who contributed fixes, used
|
|
one by Stephen Leavitt <stephen_j_leavitt@hotmail.com> who's fix was the
|
|
simplest and was backwards compatible with php3]
