$itemsToAdd was never initialized. Although not strictly required by PHP, it is generally a good practice to add $itemsToAdd = array(); before regardless.

The expression $documentData of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

                    if (isset($documentData['parents'])) {
                        foreach ($documentData['parents'] as $parent) {
