This was discussed for PHP6, but eventually decided not to have such a
function. Instead, we now have the following: $var = $_GET['var'] ?: 5;
Taken from http://www.corephp.co.uk/archives/19-Prepare-for-PHP-6.html
'you'd be able to do something like this: "$foo = $_GET['foo'] ?: 42;"
(i.e.
if foo is true, $foo will equal 42).'
