Simple PHP Domain Name checker with history

Screenshot

Quick start

Requirements

• PHP 7.4+ with CLI and webserver support
• outbound network access for whois queries (port 43) or a local whois binary

Run locally (simple):

Start PHP built-in server from the project root:

php -S localhost:8000

Open http://localhost:8000/ in a browser.

Notes

• The app uses a small WhoisService that queries known whois servers
• edit config.php to modify list of whois Top Level Domains
• History is stored in the PHP session. The frontend saves a summary of available TLDs after each check.
