phpwhois_functions.php

You have to include (per require_once() ) this file to use the WhoIs-Functions.

There is no real API, yet.  Just one function that will open an popup-window and display some whois data for a given IP.

For advanced usage, see phpwhois/README and write your one code.

to generate a clickable link which will open a popup-window use this

if(file_exists(WB_PATH.'/modules/geoip/phpwhois_functions.php')) {
  require_once(WB_PATH.'/modules/geoip/phpwhois_functions.php');
}
...
if(defined('WHOIS_LOADED')) {
  $whois_link = geoip_whois_link($ip_addr);
  echo $whois_link;
}

But since phpwhois is part of GeoIP-Module, there is no need to check against WHOIS_LOADED if GeoIP is required.  In that case you may use this

require_once(WB_PATH.'/modules/geoip/phpwhois_functions.php');
...
$whois_link = geoip_whois_link($ip_addr);
echo $whois_link;

The output may look like this

<a href="http://www.example.org/modules/geoip/phpwhois_popup.php?IP=200.10.40.1"
   onclick="return geoip_popup(this.href);" title="WhoIsQuery"
   target="_blank">200.10.40.1</a>

A typically WhoIs-Query may look like this
