<?php

include("chilkat.php");

$success = false;

$json = new CkJsonObject();

$jsonStr = '{ \'id\': 1, \'name\': \'A green door\', \'tags\': [\'home\', 22, \'green\'], \'price\': 125 }';

$success = $json->Load($jsonStr);
if ($success != true) {
    print $json->lastErrorText() . "\n";
    exit;
}

// Get the "tags" array, which contains "home", 22, "green"
// tagsArray is a CkJsonArray
$tagsArray = $json->ArrayOf('tags');
if ($json->get_LastMethodSuccess() == false) {
    print 'tags member not found.' . "\n";
    exit;
}

// Get the value at each array index. 
// Output will be:
// [0] = home
// [0] as integer = 0
// [1] = 22
// [1] as integer = 22
// [2] = green
// [2] as integer = 0

$arraySize = $tagsArray->get_Size();

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

    $sValue = $tagsArray->stringAt($i);

    print '[' . $i . '] = ' . $sValue . "\n";

    $iValue = $tagsArray->IntAt($i);
    print '[' . $i . '] as integer = ' . $iValue . "\n";

}

// Note: The StringAt method returns the value as a string regardless of the type.

// The IntAt method returns the value as an integer.  If the value does not convert to 
// an integer, then 0 is returned
