What is php-whois?

php-whois is a small PHP tool that lets you look up WHOIS information for any domain name. In practical terms, that means you can check who owns a website address, whether it's already registered, and other public registration details like the registrar or expiration date. It's the kind of thing you'd use if you wanted to build a domain availability checker into your app. The tool is designed to be dropped into an existing PHP project. You include the class file, pass in a domain name, and it gives you back the raw WHOIS data. It also provides a simple method to check if a domain is available or already taken, so you don't have to parse the WHOIS response yourself to figure that out. This would be useful for founders or builders creating domain-related tools, think of a domain name search feature on a web hosting site, or a script that checks whether a list of desired domains has become available. If you're building something where users need to know if a name is up for grabs, this handles the lookup for you. The project is straightforward and lightweight. The README doesn't go into detail about features beyond the basic lookup and availability check, so if you need more advanced parsing or bulk queries, you'd likely need to build that on top yourself. It's essentially a single PHP class that does one job without much ceremony.
