Answer 3

The two people above said the same thing, so I won’t say more. The question is, is your json a standard json? If so, I just assume that you collect it from JD.com (not counting JD.com providing it to you) ), the json obtained is used by javascript, which is not standard for php. You must complete the quotation marks before it can be used by php
