fsockopen to curl

[TapanB]

Hi,

Currently i am using this code to connect to a server get some info. and disconnect. But the problem is that its too slow and i am not sure why.

So someone told me to use cURL to speed things up ...can anyone tell me how do i achieve the same by using cURL ?

Thanks.

<?
$svr = "sub.main.com";
$port = 123;
$url = "someurl.com";

$f = @fsockopen($svr, $port, $errno, $errstr, 30);

if (!$f)
{
        return 10;
}
else
{
        $rawoutput = "";
        fputs($f, "$url\r\n");

        while (!feof($f))
        {
                $rawoutput .= fread($f,128);
        }

        fclose($f);
}
?>

Every method you use is going to do the same thing in the end -- open a connection to the server and read a response. Have you tried pinging and tracerouting to this server from yours to see if the delay is in the network?

Look up the PHP manual for cURL functions, it is quite simple.
Anyways, what speed do you expect? Using a remote server to get data from will always take awhile, maybe more depending on server speeds.
Perhaps an alternative solution is required. If you must get the data from an external source, cache the data and update at a set time interval, that way users are not affected by the slow speed.

Hi,

This is basically a whois lookup script. By which a user enters a domain name and it checks the availability of the domain b connecting to the corrosponding whois server.

Now i have taken the server list from Matt's Whois Lookup Script...its works fine also but in the end the problem is that if a user selects 5-6 extensions then it takes too much time unlike other websites which displays results much faster which also check for similar domains.

I am only checking the user specified domain name and that is taking too much time. Check at http://www.avissoftware.com.

Also i would like to know how to make a ping utility in php to check server's speed ?

Thanks.

Could use an existing PHP script like PHPWhois.

TapanB, I see your problem now, thankyou for the explanation

Take into consideration:
- The domain name registrars probably have a faster server to work with
- They probably have their own database of available domains (goes back to the caching idea I mentioned, they maintain a list, periodically run a check and updates the cached version and the clients don't wait as the script accesses this cached version in little time)
Disclaimer: The above were my "educated" guesses.

http://phpclasses.org has code for pinging and many other HTTP/network related utilities
