?: PHP Coalesce
I've often been a fan of Javascript's way of using the logical OR operator as a coalescing operator, or way to default values. It's a very handy operator for shortening ternary expressions.
var myValue = someOtherValue || true;
I just found out in PHP 5.3 they added an operator to do just that. ?:
$myValue = $someOtherValue ?: true;
That's all, carry on.
