如何在BigQuery PHP SDK中设置WRITE_TRUNCATE？

use Google\Cloud\BigQuery\BigQueryClient;
use Google\Cloud\BigQuery\WriteDisposition;

// 创建 BigQuery 客户端
$bigQuery = new BigQueryClient();

// 设置要写入的数据集和表名
$datasetId = 'your-dataset-id';
$tableId = 'your-table-id';

// 创建要写入的数据
$data = [
    ['John', 'Doe'],
    ['Jane', 'Smith']
];

// 设置写入操作为覆盖模式
$options = [
    'writeDisposition' => WriteDisposition::WRITE_TRUNCATE
];

// 执行写入操作
$table = $bigQuery->dataset($datasetId)->table($tableId);
$table->insertRows($data, $options);
