(PHP ActiveX) Iterate JSON where Member Names are Data Values

Demonstrates how to parse JSON where member names are not keywords, but instead are data values.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");

$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->Size;

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

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

    print $name . ':' . "\n";
    // jRecord is a Chilkat.JsonObject
    $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";
