Can || operator is used to choose between values of non-boolean types in PHP?

Question

Is it possible to use echo with ||so that it uses the first variable that evaluates to true?

eg,

$a = false;
$b = 'b';
echo $a || $b || 'neither'; // evaluates to 1 ?

Ultimate triple

$a = false;
$b = 'b';
echo ($a)?$a:(($b)?$b:'neither');

echo $a ? $a : ($b ? $b : ($c ? $c : 'neither'));

And you continue if you have more variables, but will be too ugly and hard to read if too long.
