whois again

rebecca

Hi all,

still working on my whois class but I'm not getting the expected results from the tiny wee bit of code I'm testing at the moment. If anyone can help I will be eternally grateful.

I put in the following code and then I get the extension listed as the last three parts of anything I put in ('one.two.three.four', extension will be listed as 'two.three.four', name will be 'one'). The point is that the code is supposed to look in the domaintype table of my database and then if a matching 3-part extension exists separate the name and parts accordingly and if not then shunt over one part of the extension to the name part and try for a match on a 2-level extension, and then a one level extension. For instance, input 'blah.com', it looks through the domaintype table, there is no 'blah.com' listed as an extension so 'blah' becomes the name and it searches for a 'com' extension, com exists in the table so we can then extract certain information from the database about the .com registry (or whatever).

<?php

class WhoisClass {
var $DB = 0;
var $wholedomain = ""; //name.extn
var $name = "";
var $extn = "";

var $errArray = array ();
var $errstr = "";

var $whois = "";
var $whoisport = "";
var $whoisip = "";
var $whoisrecurse = "N";
var $validpattern = "";
var $availablepattern = "";

var $extnhandler = "";

var $BUFFER = 0; //read buffer char by char

var $rawwhoisArray = array();
var $resultArray = array();

// constructor
function WhoisClass($newDB, $domainName) {
$this->DB = $newDB;
$this->wholedomain = strtolower(preg_replace("/[\n\s]/", "", $domainName));
$domparts = explode('.', $this->wholedomain);
$last = array_pop($domparts);
$negOne = array_pop($domparts);
$negTwo = array_pop($domparts); //to cope with 3-level tlds

	$this->name = implode ('.', $domparts);
	// for 3-level
	$this->extn = $negTwo.'.'.$negOne.'.'.$last;
	//see if can find a matching 3-level extension in the db
	$extnMatched = $this->match_extn($this->extn);
	if ($extnMatched = TRUE) {
	  //proceed with whois

	} else {
	  //we push the 'first extension bit' from the extension onto the name to create a 2-level extn
	  $domparts = array_push($domparts, $negTwo);
	  $this->name = implode('.', $wholedomain);
		$this->extn = $negOne.'.'.$last;

	}//end 2-level match
}//end constructor

function match_extn($extn){
$match_result = $this->DB->query("SELECT * FROM domaintype WHERE suffix = '$this->extn'");
if(!empty ($match_result)) {
//take out what we need from the domaintype table by item name
//$myrow = mysql_fetch_array($match_result)
//$myrow["whois"] = $this->whois;

		$this->extnMatched = TRUE;
		return $this->extnMatched;
  } else {
	  $this->extnMatched = FALSE;
		return $this->extnMatched;
	}//end else
}//end function

}//end class

I should say that it doesn't seem to do anything past saying that the last three bits of whatever I put in are the extension, if there are four or more bits then I get a name aswell, otherwise not :-(

ah, and I am now getting a message saying i have missing arguments for the whois class and the match_extn class (arg 3 and arg 2 respectively). Is it a problem with passing the extnMatched variable?

please help, I'm starting to feel quite dispirted about the whole thing and I don't think I'd really take to chicken farming . . .

thanks, reb

rebecca

I got rid of the missing args error, but still no joy with the other problem

the results of these three queries came back as follows . . .

one.two.three.four
(tld: two.three.four) name: one

one.co.uk
(tld: one.co.uk) name:

one.two.co.uk
(tld: two.co.uk) name: one

c'mon everyone, wake up and help. I'm running a very sad little thread here all by myself . . . (sob).

Aight, Reb, I'll give this a shot. I think I have an idea that I'll play around with and see what happens (basically, I don't like the negOne,negTwo idea, but not totally sure yet)... I'll post something again soon.

amcgrath

I'm not completely sure, and I haven't really debugged this (damn work, keeps getting in the way)...

$this->DB = $newDB;

/************************************
$last = array_pop($domparts);
$negOne = array_pop($domparts);
$negTwo = array_pop($domparts); //to cope with 3-level tlds
**************************************/

// instead of assigning values like above, put the combinations
// into an array so it can cope with x-level tlds

$pieces = count($domparts);

for ($x = 0; $x <= $pieces - 1; $x++) {
for ($pos = $x; $pos <= $pieces -1; $pos++) {
$extn[$domparts[$pos]];
}
$extn = implode(".",$extn);

if (!match_extn($extn) {

// no match found
continue 2;

} else {

// a match was found
break 2;
}

}

Let me know if I'm on the right track for you.

hey! I could give you a big kiss for working on this for me - really appreciated :-)

This looks like a much better way to do it. I didn't know that you could ask a function whether it succeeded or not (!match_extn($extn)) - this is what's happening here isn't it? Saves a lot of repetitive code then. Does it also mean that I can leave out the $extn_matched variable as a checking device?

I know what you mean about work. You go, you spend 8 or nine hours, and not only do they expect you to be productive, but they expect you to be productive /for the company/!

amcgrath

I'll answer each point:

You: hey! I could give you a big kiss for working on this for me - really appreciated :-)

Me: God, I love this programming stuff! 😉

You: This looks like a much better way to do it.

Me: Of course it is.

You: I didn't know that you could ask a function whether it succeeded or not (!match_extn($extn)) - this is what's happening here isn't it?

Me: Yep on both counts.

You: Does it also mean that I can leave out the $extn_matched variable as a checking device?

Me: Naw, leave it there.

Me again: I didn't debug it though, so please let me know if it works for you.

rebecca

will do. But it's finally time to go home so I shall let you know tomorrow morning :-)

rebecca

It accused me of double posting and threw away my post!!!! Life is so not fair! Excuse me while I go and have a good cry.

Okay. Writing in notepad and cutting and pasting. Trying out the whole cautious approach.

$pieces = count($domparts);

for ($x = 0; $x <= $pieces - 1; $x++) {
for ($pos = $x; $pos <= $pieces -1; $pos++) {

//what is the reason for having two things that do the same thing?
//I can't see where $x is used apart from having $pos set to it before
//$pos goes through the same count . . .
//also, if we're looking for extn's, should we look from position
//one rather than position 0?

$extn[$domparts[$pos]];

//and so $extn is used as an array of the $dompart in such and such a
//position? Is this a correct interpretation of the code?
//I may just have the wrong end of the stick completely - I was out
//with a group of student friendslast night and the wretches
//don't have to get up in the morning.

}
$extn = implode(".",$extn);

//this is where I'm getting my current parse error. ?

if (!match_extn($extn) {

// no match found
continue 2;

} else {

// a match was found
break 2;
}
}
//also had errors on the break and continue so changed them to 1 instead
//of 2 and the error messages dissappeared.
//was this bad and wrong of me?

Thankyou, thankyou, thankyou for helping (and hopefully continued help :-)
lv, reb

They're not (well, yea... they are)... but I need $pos to start at an incrmented postion for each $x iteration....

IE:
First $x interation
0= www
1= yahoo
2= com

So I check to see if www.yahoo.com is in the database.... ansewer = no

Second $x iteration
0 = yahoo
1 = com

See what I mean?

//and so $extn is used as an array of the $dompart in such and such a
//position? Is this a correct interpretation of the code?

Yes, exactly. Tehre are other ways to do it, this is just more visiually understanding.

//this is where I'm getting my current parse error. ?

Add another ) ... I left it out (Do i have to do everything? 😉

//also had errors on the break and continue so changed them to 1 instead
//of 2 and the error messages dissappeared.
//was this bad and wrong of me?

Yea, most likely this error a result if missing parens above.

Let me know if its working...
