Answer 1

I usually namespace my constants, if I’ve got many of them, in a class like so:

class Foo {
    const Bar = 1;
    const Baz = 2;

    public static $array = array(1,2,3);
}

echo Foo::Bar; # Accessing the constants
print_r(Foo:$array);

Putting an Array in a constant is not possible for class constants, and I don’t think it is a good practice putting them in global constants either, if it is even possible (not sure). Maybe you should tell us what you are trying to accomplish, maybe there is a better way to do it.

Oh, and please don’t do something like this:

for($x=0; x<10; $x++) {
    define('VAR_' . $x, 'Information #' . $x);
}

Which has been suggested here, but IMHO this is absolutely not how constant are supposed to be used.
