Если вы склонны понижать этот вопрос, пожалуйста, укажите причину, чтобы я мог учиться на своих ошибках.Почему json_encode возвращает массивы вместо объектов?

Это не обязательно, что всегда 'json_encode' возвращает объект, Попробуйте' JSON_FORCE_OBJECT' в качестве второго параметра 'json_encode'. –
Ваша строка JSON некорректно отформатирована, поэтому она выбрасывает эту ошибку, вы можете вставить свою json-строку, чтобы я мог понять, что с ней не так ... –
@ron: при первом образе вашей ошибки это похоже, что вы добавляете две строки json и отправляете их как ответ клиенту, который вам не нужен. –
