Right. Thanks. So that mean that if I want the result of a function in
an output statement I should put it in a variable prior to the output
statement?

Like this:

$ck=key($_COOKIE);
echo "The key is $ck";

rather than:

echo "The key is key($_COOKIE)";

Which I know won't work and is why I thought the curly braces was meant
to resolve, but I guess I misread/misunderstood that part as well.
