<?php

include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0

$json = new CkJsonObject();

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

// Imagine we have JSON such as the following:

// {
//   "1680": {
//     "entity_id": "1680",
//     "type_id": "simple",
//     "sku": "123"
//   },
//   "1701": {
//     "entity_id": "1701",
//     "type_id": "simple",
//     "sku": "456"
//   }
// }
// 

// This presents a parsing problem because the member names, such as "1680"
// are not keywords.  Instead they are data values.  We don't know what they
// may be in advance.  

// To solve, we iterate over the members, get the name of each, ...
$numMembers = $json->get_Size();

for ($i = 0; $i <= $numMembers - 1; $i++) {

    $name = $json->nameAt($i);

    print $name . ':' . "\n";
    // jRecord is a CkJsonObject
    $jRecord = $json->ObjectAt($i);

    print 'entity_id: ' . $jRecord->stringOf('entity_id') . "\n";
    print 'type_id: ' . $jRecord->stringOf('type_id') . "\n";
    print 'sku: ' . $jRecord->stringOf('sku') . "\n";
