Variable help

[benny_g]

I have some cookies set with the names;

poll-1,
poll-2,
poll-3,
etc.

I want to access the variable poll-3 by constructing the variable name using "$poll-" . "3"

Is this possible or does a variable name have to be hard coded?

Thanks for any help,

Ben

$x = "some_var_name";
$$x = "A value";
echo $$x;
