Как извлечь данные php

На сайте wordpress c использованием плагина woocomerce в момент формирования заказа я получаю переменную

$items = $order->get_items(); (это детали заказа)

Переменная $items Содержит

    {"id":208,"order_id":661,"name":"Комплект документов","product_id":594,"variation_id":0,"quantity":1,"tax_class":"","subtotal":"0","subtotal_tax":"0","total":"0","total_tax":"0","taxes":

Ка мне правильно вытащить данные самого заказа для дальнейшей обработки

Должно получится что то вроде:

Из {"id":2386,"key":"Фaйл(ы)","value":"https://eee.org/uploads/va2chairzby-1-_1540975698.jpg; https://eee.org/uploads/014-egrp-arh...540975703.pdf; https://eee.org/uploads/010-egrn-obekt-moskovskaya-oblast-shhelkovskij-r-n-g-shhelkovo-mkr-bogorodskij-d-17-pom-77_1540975708.pdf;"}

получить

$dow_file = "https://eee.org/uploads/va2chairzby-1-_1540975698.jpg; https://eee.org/uploads/014-egrp-arh...540975703.pdf; https://eee.org/uploads/010-egrn-obekt-moskovskaya-oblast-shhelkovskij-r-n-g-shhelkovo-mkr-bogorodskij-d-17-pom-77_1540975708.pdf;"

из

{"id":2387,"key":"Объект","value":"Москвa, ул. Неизвесная 123"}

получить

$input_obj_name = "Москвa, ул. Неизвесная 123"

из

{"id":2388,"key":"Кв.","value":"4444"}

получить

$input_obj_flat = "4444"

из

{"id":2389,"key":"Доп.","value":"99999999999"}

получить

$input_obj_kad = "99999999999"

и т.д. значение "id" конечно же каждый раз разные а значение "key" - неизменны.
