Bulk AJAX .com / .net Availability Scanner

[RyanAM]

Just threw this together really quickly because I was bored.

It's just a simple availability scanner that checks only .com and .net domains, and puts the available ones into a list. It utilizes AJAX so you can scan domains in real time without waiting for a page to load.

<?php
	function domain_status($domain){
	   $domain = strtolower($domain);
	   $o = 0; $whois = '';
	   
	   $connection = @fsockopen('whois.verisign-grs.com', 43);
		if ($connection) {
			@fputs($connection, $domain ."\r\n");
			while (!feof($connection)) {
				$whois .= @fgets($connection, 128);
			}
		 }
		fclose($connection);
		
		if(strstr($whois,"No match for")){
			$result = "<font color=green><b>Available</b></font>";
			$o=1;
		}
		
		if($o != 1){
			$result = "<font color=red><b>Taken</b></font>";
		}
		
		if(!strstr($domain,'.')) die('<b>Not a domain...</b>');
		if((!strstr($domain,'com') && !strstr($domain,'net'))) die('<b>.COM / .NET Only</b>');
		die($result);
	}
	
	if(@$_GET['domain'] != '' && @$_GET['check'] == 'true') domain_status(@$_GET['domain']);
?>

Just copy the code and save it as whatever you want .php, uploaded it to a server with PHP and doesn't restrict socket connections, and you're ready to go.
