Bagaimana cara mengambil dua respons Json Objek dan Array Json

CATATAN :seperti yang disebutkan dalam pertanyaan sebelumnya, string JSON yang diberikan harus dalam format yang benar yaitu memiliki kunci untuk setiap objek (login, akun) atau memilikinya dalam satu larik (input). Saya memberikan solusi untuk kedua opsi tersebut.

Pemula, saya memberi Anda 2 metode terpisah sehingga Anda dapat menangani string JSON yang masuk tergantung pada bagaimana Anda membangunnya baik 2 objek dalam String JSON tunggal atau 2 objek dalam array JSON.

Anda dapat memilih solusi Anda :)

Coba kodenya, beri tahu saya jika Anda membutuhkan bantuan lebih lanjut dan terima jawabannya.

OPTION1 :2 Objek dalam string JSON tunggal

{
   "login":{
      "error":false,
      "user":{
         "br_code":12,
         "mem_id":13,
         "username":"novalyn",
         "email":"[email protected]",
         "created_at":"2016-07-22 09:05:21"
      }
   },
   "accounts":{
      "error":false,
      "sl_summ":[
         {
            "sl_desc":"PA : Savings Account",
            "tr_date":"2015-08-17",
            "actual_balance":"483.67",
            "available_balance":"483.67"
         },
         {
            "sl_desc":"PA : Savings - Cash Bond",
            "tr_date":"2015-08-28",

            "available_balance":"10129.43"
         }
      ]
   }
}

OPTION2 :2 Objek dalam string array JSON tunggal

            "username":"novalyn",
            "email":"[email protected]",
            "created_at":"2016-07-22 09:05:21"
         }
      },
      {
         "error":false,
         "sl_summ":[
            {

               "available_balance":"483.67"
            },
            {
               "sl_desc":"PA : Savings - Cash Bond",
               "tr_date":"2015-08-28",
               "actual_balance":"10129.43",

            }

Saya tidak memiliki akses ke semua file PHP internal yang dapat saya gunakan untuk menjalankan Kode PHP Anda, jadi saya mengganti sebagian besar dari semua panggilan fungsi dengan nilai kode keras seperti yang dibagikan dalam contoh payload respons. Berikut adalah kode untuk menghasilkan Objek JSON dalam format OPTION1.

Singkatnya, Anda harus menambahkan ["login"] dan ["accounts"] di depan semua sub atribut di $response sehingga mereka akan dikelompokkan dalam Objek JSON yang benar dan Anda akan memiliki dua objek JSON yang dapat diuraikan dengan di atas kode bersama android.

<?php
// json response array
$br_response = array("error" => FALSE);
$sl_response["error"] = FALSE;
$sl_response["sl_summ"] = array();

$arclass = "13";
$loanclass = "12";
$accintreceivable = "21";

        // user is found
        $response["login"]["error"] = FALSE;
        $response["login"]["user"]["br_code"] = 12;
        $response["login"]["user"]["mem_id"] = 13;
        $response["login"]["user"]["username"] = "novalyn";
        $response["login"]["user"]["email"] = "[email protected]";
        $response["login"]["user"]["created_at"] = "2016-07-22 09:05:21";
                 for($i = 0; $i < 2; $i++){
                        $item = array();
                        $item["sl_desc"] = "PA : Savings Account";
                        $item["tr_date"] = "2015-08-17";
                        $item["actual_balance"] = "483.67";
                        $item["available_balance"] = "483.67";
                        $sl_response["sl_summ"][] = $item;
                    }
                    $response["accounts"] = $sl_response;
                    json_encode($response);
                    echo json_encode($response, true);

PHP Sample Run menghasilkan respons JSON (OPTION1)

{
   "login":{
      "error":false,
      "user":{
         "br_code":12,
         "mem_id":13,
         "username":"novalyn",
         "email":"[email protected]",
         "created_at":"2016-07-22 09:05:21"
      }
   },
   "accounts":{
      "error":false,
      "sl_summ":[
         {
            "sl_desc":"PA : Savings Account",
            "tr_date":"2015-08-17",
            "actual_balance":"483.67",
            "available_balance":"483.67"
         },
         {
            "sl_desc":"PA : Savings Account",
            "tr_date":"2015-08-17",
            "actual_balance":"483.67",
            "available_balance":"483.67"
         }
      ]
   }
}
