======================

위 Json을 아래와 같이 찝었습니다.

            $wr_3  = $response->businesses[0]->hours->open[3]->start;             $wr_4  = $response->businesses[0]->hours->open[3]->end;             $wr_7  = $response->businesses[0]->name;             $wr_8  = $response->businesses[0]->rating;             $wr_9 = $response->businesses[0]->is_closed;             $wr_10  = $response->businesses[0]->categories[0]->title;

다 나오는데 3,4, 번이 안나오네요.

            $wr_4  = $response->businesses[0]->hours[0]->open[0]->end;

이렇게 해도 안나왔어요.

어떻게 해야 "2200" 라는 시간을 찝을 수 있을까요?
