It's different. You can manipulate variables in some ways you can't with
constants.
This code, for example:
$a = 'abc';
$b = 'a';
print($$b);
It will display "abc". It's currently not possible to do something similar
with constants.
I think the subject was already debated, but I wonder why we should write
that:
final $foo = 'bar';
instead of:
const $foo = 'bar';
