RussianQuestion
I am using a library (Solarium for Solr), and the results returned by it is in a format that I am not familiar with. The chunk of code below shows the output of print_r($resultset) on the results $resultset returned by the library's function.
I would like it to be in a format (maybe array?) where I massage the data further, and convert it into the final format JSON. How can I do that? json_encode($resultset) just gave me an empty JSON string {}.

PHP Code
public function action_search() {
Solarium_Autoloader::register();
$client = new Solarium_Client();
$query = $client
->createSelect()
->setRows(2);
$resultset = $client->select($query);
echo "<pre>";
print_r($resultset);
$result = json_encode($resultset);
echo $result;
Solution
Based on the Solarium docs, I'd try something like this:
/*...*/
$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);
OTHER TIPS
$resultset = $client->select($query);
$result_array = json_decode($resultset->getResponse()->getBody())->response->docs;
$result = json_encode($result_array);
echo $result;
Result will be
[{"id":"1045","title":"White dress","description":"Ohhh its white omg fav color","score":1.0},{"id":"1046","title":"Darker tones","description":"Man this looks scary, the ring?

The response object has a lot of fields and functions, you usually want to return the response,
echo json_encode($resultset->getData());
