Class Constants
It is possible to define constant values on a per-class basis remaining the
same and unchangeable. Constants differ from normal variables in that you
don't use the $
symbol to declare or use them. Like
static members, constant values
cannot be accessed from an instance of the object (using
$object::constant).
The value must be a constant expression, not (for example) a variable, a class member, result of a mathematical operation or a function call.
