(PHP ActiveX) Loading and Parsing a JSON Array

A JSON array is JSON that begins with "[" and ends with "]". For example, this is a JSON array that contains 3 JSON objects.

[{"name":"jack"},{"name":"john"},{"name":"joe"}]

A JSON object, however, is JSON that begins with "{" and ends with "}". For example, this JSON is an object that contains an array.

{"pets":[{"name":"jack"},{"name":"john"},{"name":"joe"}]}

This example shows how loading a JSON array is different than loading a JSON object.

<?php

$strJsonArray = '[{\'name\':\'jack\'},{\'name\':\'john\'},{\'name\':\'joe\'}]';

$strJsonObject = '{\'pets\':[{\'name\':\'jack\'},{\'name\':\'john\'},{\'name\':\'joe\'}]}';

// A JSON array must be loaded using JsonArray:
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonArray')
$jsonArray = new COM("Chilkat.JsonArray");
$jsonArray->Load($strJsonArray);

// Examine the values:
$i = 0;
while ($i < $jsonArray->Size) {
    // jsonObj is a Chilkat.JsonObject
    $jsonObj = $jsonArray->ObjectAt($i);
    print $i . ': ' . $jsonObj->stringOf('name') . "\n";

    $i = $i + 1;
}

// Output is:

// 	0: jack
// 	1: john
// 	2: joe

// A JSON object must be loaded using JsonObject
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jsonObject = new COM("Chilkat.JsonObject");
$jsonObject->Load($strJsonObject);

// Examine the values:
$i = 0;
$numPets = $jsonObject->SizeOfArray('pets');
while ($i < $numPets) {
    $jsonObject->I = $i;
    print $i . ': ' . $jsonObject->stringOf('pets[i].name') . "\n";
    $i = $i + 1;
}

// Output is:

// 	0: jack
// 	1: john
// 	2: joe
