The final keyword was added to PHP5.
The const keyword supports some basic expressions.
I know that the const keyword is evaluated at compile time, is there
another way to create a constant object? What I need to have is an
object that is read only.

What a work in Zend2 !!! It is getting great, but what about final
classes and object constants in class definition?
I need to do something like this:
class EnumException extends Exception{ }
final class Car {
//private
const _ferrari = 0;
const _porsche = 1;
const _corvette = 2;
//private
const _last_value = 2;
//public
const ferrari = new Car(_ferrari);
const porsche = new Car(_porsche);
const corvette = new Car(_corvette);
private $value;
protected function __construct($value) {
if (($value < 0) || ($value > _last_value)) {
throw new EnumException();
}
$this->value = $value;
}
public function value() {
return $this->value;
}
}
Everything works fine, except the "final" keyword and the "const"
initialization with an object.
I think final classes would be a good approach in assuring that a class
will not be modified(inherited).
Why canīt objects be assigned to constants ? Is there another way of
doing this in Zend2 ?
Thanx,
Cristiano Duarte
