<?php

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

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

$success = $json->Load($jsonStr);
if ($success != 1) {
    print $json->LastErrorText . "\n";
    exit;
}

$numMembers = $json->Size;

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

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

    print $name . ': ' . $value . "\n";

    $iValue = $json->IntAt($i);
    print $name . ' as integer: ' . $iValue . "\n";

}

// Note: The StringAt method returns the value as a string regardless of the type.
// If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
// of the entire array is returned.

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