How would I go about making a custom Whois look up

Question

I want to add a custom Whois look up to my site. I've looked around but haven't found much information.

Answer 1

Here's a great simple PHP whois script. It's free, and just has a couple functions you can call.

Use the following php

and call the php in the page where you are going to implement

1. Upload whois.php file on your server and open in your browser: http://www.yourdomain.com/whois.php
2. Enter the domain name (only the name itself, without http://www) or IP address you want to get whois data.
3. View results online.
