Given two lists, find the common items. E.g. given beans =
php
clojure
cpp C++/CLI .NET 2.0
Submit a new solution for php, clojure, or cpp

['broad', 'mung', 'black', 'red', 'white'] and colors = ['black', 'red', 'blue', 'green'], what are the bean varieties that are also color names?
$result = array_intersect($beans, $colors);
sort($result); // just to clean it up :)
sort($result); // just to clean it up :)
