Retrieve value from json_encode with callback function on PHP

Question

How can I get my values from json_encode with a callback function

data({
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "authError",
    "message": "Invalid Credentials",
    "locationType": "header",
    "location": "Authorization"
   }
  ],
  "code": 401,
  "message": "Invalid Credentials"
 }
});

I want to get the values of my response body so that I will know if there's an error using PHP. I need to have a callback function to easily get my values via javascript.

getThis({"data":"1234"}); is JavaScript, not JSON, so obviously json_decode won't work. What are you trying to do exactly? — netcoder

@netcoder Yeah, but I'm working on a server to client app. Calling the data on the server with a callback via Javascript. But the real problem is in here (stackoverflow.com/questions/8953195/…) that's why I want to manipulate this data to know if there's any response error. — Kamina

As said in the other question's answer, the HTTP request response code will tell you if there's an error, not the response body. Just check the HTTP response code, no JSON parsing required. — netcoder

Assuming you meant var_dump($response) not var_dump($result) and I understand you properly, json_encode has converted your function to a string as you cannot convert a function to json and vice versa only arrays, objects and primitives such as strings.

This maybe a help... PHP json_encode and javascript functions
