prop-helper.php

function _getProp(string $prop, object $obj) {
    $r = new ReflectionClass($obj);
    $hasProp = $r->hasProperty($prop);
    $getter = 'get' . ucfirst($prop);
    $hasGetter = $r->hasMethod($getter);
    return match (true) {
        $hasProp && $r->getProperty($prop)->isPublic() => $obj->$prop,
        $hasGetter && $r->getMethod($getter)->isPublic() => $obj->$getter(),
        default => null
    };
