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';
