PHP assignment with a default value

Question

What\'s a nicer way to do the following, that doesn\'t call f() twice?

$x = f() ? f() : \'default\';

Answer 1

You could save it to a variable. Testcase:

function test() {
        echo 'here';
        return 1;
}

$t = test();
$x = $t ? $t : 0;
echo $x;
