get extension of a file

Hi all,
I used to use this for getting the extension of an uploaded file..
$ext = strstr($doc, ".");

but apparently this not work when the filename contain a '.'

What is the best way to get the correct extension of a file???
Thanks for your suggestion.

preg_match('/\.([^.]+)$/',$string,$match);
or
strrchr($string,'.');

$ext = pathinfo($doc, PATHINFO_EXTENSION);

Ah, that's what I was looking for, thank you. Kept ending up in the finfo*
functions for some reason (which are commonly more usefull then extensions
offcourse).
