<?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();

// To add a large integer, use AddNumberAt.

// (an index of -1 indicates append).
$index = -1;
$json->AddNumberAt($index,'bignum','8239845689346587465826345892644873453634563456');

// Do the same for a double..
$json->AddNumberAt($index,'double','-153634.295');

$json->put_EmitCompact(false);
print $json->emit() . "\n";

// Output:

// 	{
// 	  "bignum": 8239845689346587465826345892644873453634563456,
// 	  "double": -153634.295
