Checking values of Json array using PHP

Question

I have a json respond that I want to check and return values accordingly: the Json code is:

{
 "success": "true",
 "result": "ok"
}

And I need to check the success status and return an array to the controller accordingly.

I was trying to decode and ask questions on the value as follow:

$obj = json_decode($response,true);
    if ($obj['success'] =='true')
      return array(
        'error' => 0,
        'msg' => sprintf("successfully")
      );

I am not sure what i am doing wrong since I can't get the 0 in the error on array returns.

There is another json code that I need to deal with and it is this:

Negative Response:

{
“success” : “false” ,
“error”:{
        “code”:"MANDATORY_FIELDS_MISSING",
        "message”: “Phone number is a mandatory field"
    }
}

The same goes with this.

I would be happy if you couls assist me with gettin it to work properly. Thank you. Arye

Are you sure the JSON contains the string "true", not the boolean true? — Barmar

Your negative response is not valid JSON. You have to use ASCII double quotes, not curly quotes, around strings. Is that a copying error? — Barmar

Actually your code working fine. You are confused with printing and returning. Please check this:--

<?php 

$response = '{"success": "true","result": "ok"}';
$obj = json_decode($response,true);
    if ($obj['success'] =='true')
      print_r (array(
        'error' => 0,
        'msg' => sprintf("successfully")
      ));
?>

Output:-- http://prntscr.com/729h1o

So i think instead of return you need to print it out.

And you can use var_dump as well as echo <pre/>;print_r(your array inside if) just for look a bit good.

code:

$json = '
{
 "success": "true",
 "result": "ok"
}';

$obj = json_decode($json, true);


if ($obj['success'] == 'true')
    var_dump(array(
        'error' => 0,
        'msg' => 'successfully'
    ));

output:

array(2) {
  'error' =>
  int(0)
  'msg' =>
  string(12) "successfully"
}

When you run the code above, do you get the same output I see?
