Ответ json может иметь любое количество значений расстояния, значений длительности, шагов и ног, вложенных друг в друга. Мне нужно обеспечить исходное соединение расстояния и длительности в переменной для последующей математики. Обратите внимание, что файл также имеет значения расстояния и значения длительности, НЕ вложенные в шаги, которые я не заинтересован в сборе. Я новичок ie PHP программист - пожалуйста, будьте осторожны. Спасибо.
Вот пример ответа json в файле, извините, что он так долго.
