How to query whois information in php

This article describes the method of querying whois information in php. Share it with everyone for your reference. The details are as follows:

Here we use php to query the list of websites that query whois information

function whois_query($domain) {

// fix the domain name:

$domain = strtolower(trim($domain));

$domain = preg_replace('/^http:///i', '', $domain);

$domain = preg_replace('/^www./i', '', $domain);

$domain = explode('/', $domain);

$domain = trim($domain[0]);

// split the TLD from domain name

$_domain = explode('.', $domain);

$lst = count($_domain)-1;

$ext = $_domain[$lst];

// You find resources and lists

// like these on wikipedia:

// http://de.wikipedia.org/wiki/Whois

$output = '';

// connect to whois server:

if ($conn = fsockopen ($nic_server, 43)) {

fputs($conn, $domain."rn");

while(!feof($conn)) {

$output .= fgets($conn,128);

}

fclose($conn);

}
