从PHP向Firestore发送ArrayValue不起作用

use Google\Cloud\Firestore\FirestoreClient;
use Google\Cloud\Firestore\ArrayValue;

$firestore = new FirestoreClient();

$array = ['element1', 'element2', 'element3'];

$arrayValue = new ArrayValue();
foreach ($array as $element) {
    $arrayValue->add($element);
}

$docRef = $firestore->collection('your_collection')->document('your_document');
$docRef->set([
    'arrayField' => $arrayValue
]);
