PHP Shorthand Boolean

I'm trying to shorten the following. Essentially I want to always get the value of the lefthand as long as $object isn't null, otherwise use a default value.

if ($object) {
    $isManual = $object->getIsManual(); // either true or false
} else {
    $isManual = true;
}

The following doesn't work since getIsManual can return false which makes it use the righthand.

$isManual = $object ? $object->getIsManual() : true;

Any work arounds? Currently on PHP 7.4.

Just to clarify - the return value of getIsManual() wouldn't affect the condition, it only evaluates $object to be 'true' or 'false' (which include null).

You can explicitly check for null in the condition...

$isManual = is_null($object) ? true : $object->getIsManual();

Note that I've reversed the order of the values as I prefer to say is is_null rather than using a not as well.
