我正在使用一个库（Solarium用于Solr），它返回的结果是我不熟悉的格式。下面的代码块显示了库函数返回的结果print_r($resultset)上$resultset的输出。
我希望它是一种格式（可能是数组？），我在那里进一步按摩数据，并将其转换为最终格式JSON。我怎样才能做到这一点？ json_encode($resultset)刚刚给了我一个空的JSON字符串{}。

PHP代码
public function action_search() {
Solarium_Autoloader::register();
$client = new Solarium_Client();
$query = $client

->setRows(2);
$resultset = $client->select($query);
echo "<pre>";
print_r($resultset);

根据Solarium docs，我会尝试这样的事情：
/*...*/
$resultset = $client->select($query);
$results = array();
foreach($resultset as $document) {
$item = array();
foreach($document as $field => $value) {
$item[$field] = $value;
}
$results[] = $item;
}
echo json_encode($results);
答案 1 :(得分：1)
$resultset = $client->select($query);
$result_array = json_decode($resultset->getResponse()->getBody())->response->docs;
$result = json_encode($result_array);
echo $result;
结果将是

响应对象有很多字段和函数，你通常想要返回响应，
echo json_encode($resultset->getData());
