Не получается работать с json строкой как с массивом [дубликат]

Получаю вот такой ответ:

Хочу получить нужные мне значения из него:

$arr = json_decode($data);
foreach ($arr as $key => $value) {
    /* code */
}

Но в ответ получаю: Warning: Invalid argument supplied for foreach()

Что я упускаю? В чем моя ошибка?
