<?php /* Challenge 1: Read and write to Test::$secret before it's output. Rules:: 1. No use of Reflection API / runkit extension 2. No stopping execution before Test::run() 3. No Exceptions or PHP errors / warnings notices allowed 4. No redefining $test Hints: 1. Caesar 2. Magic methods 3. Requires a new feature of PHP 5.4 */ class Test { private $secret = 'Nyy lbhe Onfr ner orybat gb hf.'; private $callback; final public function run() { call_user_func($this->callback); return $this->secret .
