Can you design a PHP calculator using only PHP or would you need HTML for input??
I was asked this question in an interview recently and I told the guy, yes, you can make a PHP calculator using ONLY PHP.. Geez, I hope I was right..
You could write a command line script, or even a web script that returns text/plain or text/json instead of HTML.
