Demonstrates how to sort the members of a JSON object by the key name. PHP Extension

<?php

include("chilkat.php");

$json = new CkJsonObject();

$json->UpdateString('xyz','1234');
$json->UpdateString('abc.xyz','1234');
$json->UpdateString('abc.def','1234');
$json->UpdateString('abc.aaa','1234');
$json->UpdateString('ghi','1234');
$json->UpdateString('nmo','1234');

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

// This is our initial JSON:

// {
//   "xyz": "1234",
//   "abc": {
//     "xyz": "1234",
//     "def": "1234",
//     "aaa": "1234"
//   },
//   "ghi": "1234",
//   "nmo": "1234"
// }

// Sort the top-level JSON object by key.
$ascending = true;
$caseSensitive = true;
$json->Sort($ascending,$caseSensitive);

// Look at the sorted JSON..
print $json->emit() . "\n";

// {
//   "abc": {
//     "xyz": "1234",
//     "def": "1234",
//     "aaa": "1234"
//   },
//   "ghi": "1234",
//   "nmo": "1234",
//   "xyz": "1234"
// }

// Now sort the members of the "abc" object..
$jsonAbc = new CkJsonObject();
$json->ObjectOf2('abc',$jsonAbc);

$jsonAbc->Sort($ascending,$caseSensitive);

// Now look at the JSON with the members under "abc" also sorted..
print $json->emit() . "\n";

// {
//   "abc": {
//     "aaa": "1234",
//     "def": "1234",
//     "xyz": "1234"
//   },
//   "ghi": "1234",
//   "nmo": "1234",
//   "xyz": "1234"
