No need for eval() here, this will work just fine:
$x = "Cookie$i";
$y = $$x;
You could also collapse the two statements like this (if you didn't need
$x):
$y = ${"Cookie$i"};
or
$y = ${"Cookie".$i};
However, this seems to be a classic case where the use of variable variables
looks like a fudged solution, and you should examine your data to see if it
can't be better represented in an array (which would have made coding the
above loop a snap).
Cheers!
