tuberboy/code-mail ? reverse-engineered prompt

Build me a simple PHP tool for code mail checking and generating, with a way to find and match accounts automatically.

I want it to feel like a small utility I can run from the command line or through a basic web page, where I can enter a number or email and see whether it matches, generate new code mail data, and save results to a file. If it makes sense, add simple flows for checking passwords and changing account info too, but keep it lightweight and easy to use.

Make the interface straightforward, with clear messages about what was found or changed, and handle bad input politely. If you need to look up current docs or best practices online, go ahead.
