what trying print this

confidence : 0.35399999999999998 similar: test2 

well, provided valid json string, use simple json_decode() true flag returns array. example:

$data = json_decode($response->raw_body, true); $i = 0; foreach($data['photos'][0]['tags'][0]['uids'] $value) {     if($i == 5) break;     echo 'confidence: ' . $value['confidence'] . '<br/>';     echo 'similar: ' . $value['prediction'] . '<br/><br/>';     $i++; }
