*/
 
$ip = "74.65.112.23";
 
$whois = get_whois($ip);
 
echo "<pre class="brush:php;toolbar:false">$whois

"; /** Get the whois content of an ip by selecting the correct server */ function get_whois($ip) { $w = get_whois_from_server('whois.iana.org' , $ip); preg_match('@whois\.[\w\.]*@si' , $w , $data); $whois_server = $data[0]; //echo $whois_server; //now get actual whois data $whois_data = get_whois_from_server($whois_server , $ip); return $whois_data; } /** Get the whois result from a whois server return text */ function get_whois_from_server($server , $ip) { $data = ''; #Before connecting lets check whether server alive or not #Create the socket and connect $f = fsockopen($server, 43, $errno, $errstr, 3); //Open a new connection if(!$f) { return ''; } #Set the timeout limit for read if(!stream_set_timeout($f , 3)) { die('Unable to set set_timeout'); #Did this solve the problem ? } #Send the IP to the whois server if($f) { fputs($f, "$ip\r\n"); } /* Theory : stream_set_timeout must be set after a write and before a read for it to take effect on the read operation If it is set before the write then it will have no effect : http://in.php.net/stream_set_timeout */ //Set the timeout limit for read if(!stream_set_timeout($f , 3)) { die('Unable to stream_set_timeout'); #Did this solve the problem ? } //Set socket in non-blocking mode stream_set_blocking ($f, 0 ); //If connection still valid if($f) { while (!feof($f)) { $data .= fread($f , 128); } } //Now return the data return $data; }
