<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$json = new CkJsonObject();

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

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

$numMembers = $json->get_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
