Think on any finite set of elements that cannot be represented with integers
because they don't hold enough data... or because the repeated values.
An extremely example could be the "Periodic Table", finite set of elements,
where each element holds a lot of information.
function print_element(Element $e) {
echo $e->weight(), PHP_EOL,
$e->density(), PHP_EOL,
$e->protons(), PHP_EOL,
$e->neutrons();
}
print_element(Element:Hydrogen);
print_element(Element:Argon);
print_element(Element:Iron);
How do you implement this with just string=>integer define or constants?
so you need classes.. do they fit well? I don't think so
$h = new Hydrogen(); // What would mean this?
$h = Element::Hydrogen(); // probably with a static method
$h = Element::Hydrogen; // class constant? lack of objects support
