PHP Whois Script and Server List

Use this PHP class script the whois information for domain names. You can check if a domain is free or you can request the detailed whois information for already registered domain names. The whois information is used by domain name hosting providers or by a user who is looking for a free (or registered) domain name. The script comes with different example files to show you how to use the PHP class for single and multiple domain name requests.

The PHP Whois class works with TLD's (top-level domain names) where a whois server is available. You can choose which domain name extensions (tld) the script should support. A complete whois server list is attached to this page.

How does it work?

Try the basic whois domain example script first.

  1. Create on your web server the following directory structure: Your_Public_Folder/classes/whois/ (Your_Public_Folder is the directory where your site's homepage is located).
  2. Upload the class file named "whois_class.php" into this newly created directory.
  3. Upload the PHP Whois example file "whois_example.php" to your server as well and access the file in your browser.
  4. Enter into the form field the first part from a domain name and choose an extension from the select menu.
  5. Optional: Use the checkbox "Show all info?" to get also the whois information for a valid domain name.
  6. Click the submit button.

More example files:

multi_whois_list.php and multi_whois_detail.php
These two files check a) multiple domain names in a single request and b) the detail page show the whois detail (if available)

This file is an example how to redirect the user to the next page, for example the step2 in a domain name order process.

Complete Whois server list

Open the file "server_list.php" and notice that every Whois server entry has three array elements: The whois server name, the "is free" string and an optional parameter (you need to check the specific Whois server website to check if they are required). You can add to this list as many TLD’s you need, check the following Whois server list for the details.

Whois server test

There is a small script that you can use to check the response for a query with each whois server. Open the file "whois_servertest.php" and change the value for the whois server and domain name. Run the PHP script in your browser or from the command line.
