i don't quiet get your question but i think you mean this. How can you execute code written in a string?
For instance:
$sCode = "echo 'Bleep bleep';";
If you want to echo the bleep bleep by executing the string the only thing you need to do is.
eval($sCode);
et voila it says 'Bleep bleep' on your screen. Is this cooler than the Hello world! example or what!!!
HEHE
EDIT:
So the answer would be
eval($funcs["vote"]["entry"]);
I guess
BTW: Eval also exist in javascript and probably many many other languages
