If you want to extract the message value, this is OK, and there is a record of the time and content, such punishment is 17:35:24 and Beijing Tongzhou District/salesman receiving/Recipient: Zhang Meng, how to implement it?

------ Solution --------------------
Assume that the code is utf-8. otherwise, $ s = iconv ('gbk', 'utf-8', $ s) is required );

$ S = your string
$ S = strtr ($ s, "'",' "'); // Convert it to a json file that can be recognized by php.
$ T = json_decode ($ s );
Echo $ t-> message; // OK
Echo $ t-> data [9]-> context; // receiver: Zhang Meng, district, Tongzhou district, Beijing, China



------ Solution --------------------
You can use the explode function first.
------ Solution --------------------

PHP code

$current= strtr($current0, "'", '"');$json = json_decode($current);echo $json->message;$length=count($json->data);;$bottom=$length-1;echo $json->data[$bottom]->context;
