The PHP 5.3 "ternary" operator syntax (expr1?:expr3) is particularly useful when used for
setting a variable to a user value if set, or a default value otherwise.
For example:
<?php
$httpServerPort = getConfigVar('server.port')?:80;
$httpServerName = getConfigVar('server.name')?:'localhost';
$mailTitle = $_POST['title']?:'(no title)';
?>
