Odczytanie danych

Cześć,
Potrzebuję tylko odczytać pola name oraz confidence. Podpowie ktoś jak to zrobić? Z góry dziękuje za pomoc.

przecież to jest zwykły json - użyj json_decode a potem to już chyba potrafisz dobrać się do danych

Robię tak, ale zwraca mi to pustą stronę :(

$obj = json_decode($result, true);
echo $obj['Name'];

Użyj var_dump na całym $obj. I zobaczysz wtedy, co jest zwracane.

Źle to skopiowałeś i dlatego nie działa.
