Amazing
Echo json_last_error ();
The result is 4, indicating that the format is incorrect.
So I threw the returned content at http://jsonlint.com/detection, and reported an error, which is a line change problem.
Print_r (json_decode (str_replace ("\ n", "", $ result )));
The result is fine.

Thank you for not using json_last_error.
