I had the following code in PHP:
<?php
// Goal: Print "checked" if "english" is in the $languages array,
// otherwise do not print.
in_array("english", $languages) && "checked";
However this printed true instead of "checked", as I would expect in
Ruby/JavaScript/Python. This is because PHP casts the result here to true.
This is different to what happens in Ruby/JavaScript/Python (where "checked" would be returned).
