// 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");

// Imagine we have two separate JSON objects.
$jsonA = new CkJsonObject();
$jsonA->UpdateString('ciphertext','encryptedData');
$jsonA->UpdateInt('status',200);
$jsonA->UpdateString('error','errorMsg');

$jsonA->put_EmitCompact(false);
print $jsonA->emit() . "\n";

// jsonA contains:

// {
//   "ciphertext": "encryptedData",
//   "status": 200,
//   "error": "errorMsg"
// }

$jsonB = new CkJsonObject();
$jsonB->UpdateString('users[0].role','Surgeon');
$jsonB->UpdateNewArray('users[0].sub_roles');

$jsonB->UpdateBool('users[1].viewable_for_sharing',true);
$jsonB->UpdateInt('users[1].eula_create_date',123);

$jsonB->put_EmitCompact(false);
print $jsonB->emit() . "\n";

// jsonB contains:

// {
//   "users": [
//     {
//       "role": "Surgeon",
//       "sub_roles": [],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108922482
//     },
//     {
//       "role": "Support",

//       "eula_create_date": 1649108951523
//     }
//   ]
// }

// Let's say we want to insert jsonB into jsonA to get this:

// {
//   "ciphertext": "encryptedData",
//   "status": 200,
//   "error": "errorMsg",
//   "users": [
//     {
//       "role": "Surgeon",
//       "sub_roles": [],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108922482
//     },
//     {
//       "role": "Support",
//       "sub_roles": [
//         "Tech",
//         "Service"
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108951523
//     }
//   ]
// }

// First add an empty array at the desired location (-1 means append to end).
$jsonA->AddArrayAt(-1,'users');

// The destination is the empty "users" array, the source is the populated "users" array in jsonB.
// jsonUsersDest is a CkJsonArray
$jsonUsersDest = $jsonA->ArrayOf('users');
// jsonUsersSrc is a CkJsonArray
$jsonUsersSrc = $jsonB->ArrayOf('users');
// Copy the array items from source to dest
$jsonUsersDest->AppendArrayItems($jsonUsersSrc);

print $jsonA->emit() . "\n";

// The end result is this:

// {
//   "ciphertext": "encryptedData",
//   "status": 200,
//   "error": "errorMsg",
//   "users": [
//     {
//       "role": "Surgeon",
//       "sub_roles": [
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 123
//     },
//     {
//       "role": "Support",
//       "sub_roles": [
//         "Tech",
//         "Service"
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 123
//     }
//   ]
