Since I'm starting up my new webhosting and domain website, I need help with the code for the clients to search to see if their domain is available or not. If you could help me, that would be great.

INSTALLATION
SEE THE INSTALLATION.TXT FILE
VERSION 3.1.1 2004-03-10
Added some TLD's and made changes to renamed whois servers
VERSION 3.1 2003-12-28
Implemented better error handing messages to be printed right into the template
Implemented support to the server less .co.za domain using both socket and curl
based functions to query the co.za domain zone
Rewrite in the core to use a multi dimensional array for the server definitions
thanks to [ ] for pointing this out this eliminates the variable definitions
for all tlds and also the if block that supported the old decision structure
Implemented support for checking of all the supported domains at a go although
it slows performance a bit
VERSION 3 2003- 05 -20
THIS UPGRADED TO SUPPORT GLOBALS OF SERVERS
BETTER DISPLAY IN THE TEMPLATE
UPDATES TO .ORG DOMAIN WHOIS NOW TRANSFERED TO whois.publicinterestregistry.net
THANKS TO CHRIS [email protected] FOR POINTING OUT THE CHANGE TO ME SHOULD YOU FIND
A PARTICULAR WHOIS SERVER NOT WORKING PLEASE POST THAT ON THE FORUM FOR ME TO
MAKE GLOBAL CHANGES FOR THE BENEFIT OF EVERY ONE --
VERSION 2
THIS IS THE TOTALLY REWRITTEN VERSION WHICH HAS BEEN UPGRADED TO INCLUDE
1.SUPPORT FOR THE NEW REFERAL WHOIS SYSTEM.
2.ACCESS CONTROL TO AVOID BANDWIDTH THEFT
3.CHECKS FOR EXISTENCE OF TEMPLATE
4.RETURN OF FULL WHOIS DETAILS
5.REMOVAL OF ALL INTERPRETATIONS OF MATT'S WHOIS
6.RENAMED TO TOPDOG DOMAIN CHECK AND WHOIS SCRIPT FROM UGANDA DOMAIN CHECK AND WHOIS
THIS TO REFLECT OVERWHELMING INTREST FROM USERS OF INTERNATIONAL TLD's

QUERIES ON THE OUR SUPPORT FORUM @ www.topdog-software.com/forum/ BEFORE EMAILING
ME BECAUSE I RECEIVE MANY EMAILS FROM DIFFERENT USERS ASKING SIMILAR QUESTIONS
SO IF YOU POST IT ON THE BOARD AND I ANSWER IT OTHER USERS CAN USE THAT TO SOLVE
THEIR QUERIES IN THE FUTURE. By the way if you don't know anything about scripts
don't dispair we can setup custom scripts for you at a minimal fee.
Do not change the server definitions unless you know what you are doing should you
require to implement new extentions then check with iana to find out the registrar
of the extention you want then find out the address of their whois server and the
string it returns if a record is not found. You can the create a new entry under the
server definitions to reflect this.
