Sam`s Whois

Sam`s Whois is a free php class with supporting scripts which make adding a domain name whois lookup to your website incredibly simple. The scripts were written by me, Sam, hence the name. Imaginative, huh?
Main Features
- All major tlds supported (including com, net, org, info, biz, us, co.uk, org.uk, etc).
- Optionally automatically redirect a query to the authoritative whois server for a tld where appropriate (.com and .net).
- CSS-based design for easy integration with your existing website design.
- Free to use (see the licence page for full details)
- Can cache whois lookup results for a specified amount of time, reducing bandwidth and system usage.
- Optionally require users to enter a randomly generated code, displayed as an image, for each lookup to stop people using scripts to abuse the system.
- Comes with a detailed and heavily commented example script fully illustrating usage.
- Easy installation - Basic version requires only 1 line of code. View the quickstart guide here.
- Optionally clean whois data of extraneous text (for some tlds).
- Easily limit which tlds are supported with one line of code.
- Optionally hilight main fields in the whois data for extra clarity.
