I am creating a Rector (rector/rector) rule that should alter properties based on some of their attributes.

PhpParser is from nikic/php-parser.

I have no problem fetching the Properties, I simply check if current PhpParserNode is an instance of PhpParserNodeStmtProperty (and I do get matches).

However, for my use case to match some change source data, I also need the class name of the class the property belongs to – I tried following naive implementation:

    private function getClassNameFromPropertyNode(Property $propertyNode): ?string {
        $currentNode = $propertyNode;
        while ($currentNode !== null) {
            if ($currentNode instanceof PhpParserNodeStmtClass_) {
                $name = $currentNode->name;
                return $name instanceof PhpParserNodeIdentifier ? $name->toString() : null;
            }
            $currentNode =  $currentNode->getAttribute('parent');
        }
        return null;
    }

But it always gets me null … it seems that $currentNode->getAttribute('parent') this always return null.

How do I get the parent node of current node and/or the class name of the current property? Thank you.
