Here is a challenge for you then: Try to make a calculator where you can enter simple expressions and make it calculate it... Eg: 1+2*5

or make a graphing calculator using the gd library.

I suspect that's not quite what you're thinking of -

[code]<?php
echo(1+2*5);
?>[/code]

Shows 11. Just as it should.

hmm i have this sneaky feeling that someone has read that, and is hacking up some GD scripts as we speak...

It's just a good thing that I don't have to give anything tangible. :) I heart imaginary rewards. Except when I'm getting them.
