Project Euler Fibonacci Sequence?

Question

So I solved the second Project Euler challenge, but is this the best way to do this?

I can't help but feel like there's a better way to solve it.

Answer 1

You can also generate the fibonacci sequence using Phi (Φ), might want to put some research into that.

Answer 2

Three variables + a while loop instead of a for loop for less iterations. Looking forward to even better solutions.
