final, and can’t be overwritten in a child class.finalis a way to make sure a constant cannot be changed in children classes.
private constants can’t be made final, as they are not accessible to any other class.

class y extends x {
const F = 1;
const P = 2;
}
class x {
final const F = 3;
private const PRI = 5; // Private can't be final
const P = 4;
}
?>
