    This extension can be used to provide server-side and client-side form validation by executing the same JavaScript code at both places.

    You can use function variables (jay!)

    So the following works:

    $add = function ($a, $b) {
    return $a + $b;
    };
    $v8 = new V8Js('PHP', array('add' => 'add'));
    $result = $v8->executeString('PHP.add(1,2)');
    var_dump($result);

    yields indeed:
    int(3)

    v8js can be also used to render server-side javascript components (see: React.js).
