<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$json = new CkJsonObject();
$json->put_EmitCompact(false);

// Load the following JSON:

// {
//   "petter": {
//     "DOB": "26/02/1986",
//     "gender": "male",
//     "country": "US"
//   },
//   "Sara": {
//     "DOB": "13/05/1982",
//     "gender": "female",
//     "country": "FR"
//   },
//   "Jon": {
//     "DOB": "19/03/1984",
//     "gender": "male",
//     "country": "UK"
//   }
// }

$success = $json->LoadFile('qa_data/json/people.json');
// Assume success..

// Swap the positions of Jon and Sara.
$index1 = $json->IndexOf('Jon');
$index2 = $json->IndexOf('Sara');
$json->Swap($index1,$index2);

// We have this now:
print $json->emit() . "\n";

// {
//   "petter": {
//     "DOB": "26/02/1986",
//     "gender": "male",
//     "country": "US"
//   },
//   "Jon": {
//     "DOB": "19/03/1984",
//     "gender": "male",
//     "country": "UK"
//   },
//   "Sara": {
//     "DOB": "13/05/1982",
//     "gender": "female",
//     "country": "FR"
//   }
// }

// To swap an inner member:
// jsonSara is a CkJsonObject
$jsonSara = $json->ObjectOf('Sara');
$index1 = $jsonSara->IndexOf('DOB');
$index2 = $jsonSara->IndexOf('country');
$jsonSara->Swap($index1,$index2);

// We now have this:
print $json->emit() . "\n";

// {
//   "petter": {
//     "DOB": "26/02/1986",
//     "gender": "male",
//     "country": "US"
//   },
//   "Jon": {
//     "DOB": "19/03/1984",
//     "gender": "male",
//     "country": "UK"
//   },
//   "Sara": {
//     "country": "FR",
//     "gender": "female",
//     "DOB": "13/05/1982"
//   }
// }
