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

<?php

$json = new COM("Chilkat.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 = 0;
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.

//  Look at the sorted JSON..

//  Now sort the members of the "abc" object..
