Simplest way for return/echo in function (shorthand IF)

I have this function in my class. Default it should echo value, but also return value to variable by using optional parameter.

public function test($return = false) {

    $value = 'demo123';

    if ($return) {
        return $value; // optional
    } else {
        echo $value; // default
    }

}

Is there any way to make this "if" shorter, in one line (because I have a lot of functions with this so I can save many lines).

I tried ternary operators, but I don't know if I can use them in this somehow.

What's the best, correct, beauty way to do this return/echo function?
