See more JSON Examples

Demonstrates how to sort the members of a JSON object by the key name. Chilkat2 PHP

<?php

use Chilkat2\JsonObject;

$json = new JsonObject();

$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->EmitCompact = false;
echo $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..
echo $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 JsonObject();
$json->ObjectOf2('abc', $jsonAbc);

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

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

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