MongoDB PHP：从从属读取并在高读取环境下设置持久连接

php
// 创建MongoDB连接
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
// 设置从从属节点读取数据
$options = [
    'readPreference' => MongoDB\Driver\ReadPreference::RP_SECONDARY_PREFERRED
];
// 查询数据
$query = new MongoDB\Driver\Query([], $options);
$cursor = $manager->executeQuery('test.collection', $query);
// 遍历结果
foreach ($cursor as $document) {
    // 处理查询结果
    var_dump($document);
}
?>
