Help turn this fsockopen into a curl function instead

PHP
1 
$sock = fsockopen('whois.crsnic.net', 43) or die('Error Connecting To Server.');
fputs($sock, "arcadejunk.com\\r\
");
while( !feof($sock) ) { $buffer .= fgets($sock,1024); }
fclose($sock);

Is there a way to change the above code into a curl function? cUrl works faster and can do more inquires then fsockopen can do. I would like to change my whois lookup routine into a curl whois lookup routine.

Please, help.

I have been tring to use this with no luck.

$curlPost[] = "arcadejunk.com\\r\
";
if(!$ch = curl_init('whois.crsnic.net')) {
   echo "Could not connect to whois.crsnic.net";
    return;
}
curl_setopt($ch, CURLOPT_PORT, 43);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_TIMEOUT, 5);
//curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt ($ch, CURLOPT_HTTPHEADER, $curlPost);
$data = curl_exec($ch);

echo "<pre>";
  print_r(curl_getinfo($ch));
  echo "<br />cURL error number: " .curl_errno($ch)."<br />";
  echo "<br />cURL error: " . curl_error($ch)."<br />";
 curl_close($ch);
 echo "<br />$data<br />";
echo "</pre>";

I did notice a post on the libcurl website saying that the curlopt_port had a bug in it where it would not set the port correctly.

The version that is running.

libcurl/7.15.3 OpenSSL/0.9.7a zlib/1.2.1.2 libidn/0.5.6

//EDIT*******

Found it!!

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"whois.crsnic.net:43");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "arcadejunk.com\\r\
");
$data = curl_exec ($ch);
echo $data;

Try this out:


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "whois.crsnic.net");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
echo $data = curl_exec($ch);

I am not sure whether it works for you or not but this prints the contents of this url.

I have done a whois lookup rountine on my domain name tools page of the website.

http://www.nameslot.com/nametools.php

If you are interested in this code then let me know. But I can tell you that it is also using fsockopen.

rajug: That defaults to port 80, which will not work.

nameslot: I have fsockopen working. That is not the problem.

Here is the reason why I want to use cUrl instead of the fsockopen.

Performance Comparison*

10 per minute for fopen/fread for 100 HTTP files
2000 per minute for PHP/CURL for 2000 HTTP files

Okay so in short you want the contents of the given page in the $buffer variable which now is being done by fsockopen and you want to get the same thing using cURL.

Right.

So what is the problem on this:


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "whois.crsnic.net:43");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
echo $data = curl_exec($ch);

I think it is working for me here which shows this text in response.

I am not sure about this message/text but it should work like this specifying the port in the address.

You can also specify your port like this:


curl_setopt($ch, CURLOPT_PORT, 80);
