What does the program print?

PHP

<?php

$code = '2';
switch ($code) {
    case 2:
        echo 'two';
    case 3:
        echo 'three';
        break;
    default:
        echo 'other';
}

Expecting two, as if each case ended on its own: without break, PHP falls through and also runs case 3, up to its break.
Expecting other because '2' is a string: switch compares loosely with ==, so the numeric string '2' matches case 2.

What does the program print if case 2: gets its own break?
Which value of $code makes the program print other?
