const defines a class constant, while define defines a global constant. You
use const-defined constants inside class using self::constant, not
$this->constant, and a define-defined constant in a normal, non-object shit.
When using const, the value must be a static value, not a result of a
mathematical operation or function. const is restricted in many ways
compared to define, and should be used in classes/objects
