Redefining symbol midway through a document
I am trying to have one command (phi) draw two different symbols (varphi and regular phi) in the same document.
I have tried this with the below:
documentclass{article}
usepackage{amsmath, amssymb}
newcommand{oldphi}{phi}
renewcommand{phi}{varphi}
begin{document}
$phi$
renewcommand{phi}{oldphi}
$phi$
end{document}
But this wont compile (with pdftex or TexMaker), it seem like it gets stuck in a loop and wont create a pdf, but I can't see why?
Or is there a better way to achieve this?

Yes: using phi` when you want it, and `varphi`` when it is the one you need.

@Bernard I know that's the simplest way to do it really, but it would mean writing way to many extra letters :P

With let, it works:
documentclass{article}
usepackage{amsmath, amssymb}
letoldphi=phi
letphi=varphi
begin{document}
$phi$
letphi=oldphi
$phi$
letphi=varphi
$phi$
letphi=oldphi
$phi$
end{document}

letphivarphi

letphioldphi

end{document}
My understanding is that newcommand{x}{y} simply replaces "a" with "b" so can become circular, whereas letab actually sets a to the value of b, so resolves any self-referencing issues.
