Question

I have this piece of code:

return json_decode($body);

This return is from a function that gets from google some search results. If I print that it wil be for example:

stdClass Object
    (
        [responseData] => stdClass Object
            (
                [results] => Array
                    (
                        [0] => stdClass Object
                            (
                                [GsearchResultClass] => GwebSearch

                        [moreResultsUrl] => http://www.google.com/search?oe=utf8&ie=utf8&source=uds&start=0&hl=en&q=bmw+cars
                        [searchResultTime] => 0.15
                    )
            )
        [responseDetails] => 
        [responseStatus] => 200
    )

Now, I tried to get with the function get_object_vars() but the same output will come. I want to put into an array the values but only the [ur] => ; [title] => and [content]=> ; how can i achieve that?

Answer 1

Assuming that the data above is held in a variable called $returnedData:

This version works if you use return json_decode($body);:

$results = array();
foreach ($returnedData->responseData->results as $result) {
  $results[] = array(
    'url' => $result->url,
    'title' => $result->title,
    'content'=>$result->content
  );
}

print_r($results);

…and this version works if you use return json_decode($body,true);:

$results = array();
foreach ($returnedData['responseData']['results'] as $result) {
  $results[] = array(
    'url' => $result['url'],
    'title' => $result['title'],
    'content'=>$result['content']
  );
}

print_r($results);
