Access JavaScript json array in PHP

Question

I have this JSON in socket client

{ 
  "DATA":
     [
      {
       "message": my_message,
       "name": my_name,
       "id": my_id,
      }
     ]
}

And i have to decode this in socket server to respond with another JSON,like below:

$data = json_decode($received_text); //json decode 
$user_message = $data['DATA']->message; //message text
$user_name = $data['DATA']->name; //sender name

But can't access it, What is wrong in it?

please add param to part json to array json_decode($received_text, true); — HoangHieu, Jul 28 '18 at 13:55
Its an OBJECT so use `$user_message = $data->DATA[0]->message;` — RiggsFolly, Jul 28 '18 at 13:56
Why you marked it as duplicated? look it has Key , I could not find any way to solve this problem! What guys you are! @RiggsFolly — Aqil, Jul 28 '18 at 14:08
"did not work" is not very helpful, do you get any errors/warnings/notices? If you execute `var_dump($data);` what is the result? — rickdenhaan, Jul 28 '18 at 14:08
@rickdenhaan i get null response in server,but without Key i mean "DATA" ,it works without key it was like this {"TEST":test,"TEST1":test1} , note test and test1 are variables. — Aqil, Jul 28 '18 at 14:14
If the response is `null` then `json_decode()` failed. You can look at `json_last_error()` to find out why — rickdenhaan, Jul 28 '18 at 14:26
When I try to `json_decode()` the json you show us I get `syntax error` from `json_last_error_msg()` — RiggsFolly, Jul 28 '18 at 14:29
Maybe if you show us a real json string we can be of assistance — RiggsFolly, Jul 28 '18 at 14:31

You need to change your code like below

$received_text =  '{"DATA":[{"message":"my_message","name":"my_name","id":"my_id"}]}';

$data = json_decode($received_text); //json decode 
$data = $data->DATA[0];

$user_message = $data->message; //message text
$user_name = $data->name; //sender name 

echo $user_message . "<br>". $user_name;
