(PHP Extension) Demonstrates how to Handle Large Integers in JSON

See more JSON Examples

Demonstrates how to handle large integers in JSON. (Integers larger than what can fit in a 32-bit signed integer.)

PHP Extension for Windows, Linux, MAC OS X,
Alpine Linux, Solaris, OpenBSD, FreeBSD,
and Linux armhf/aarch64

<?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");

// Let's say your JSON has this:

// {
// 	"id": 20000000001234567
// }

$json = new CkJsonObject();

$success = $json->LoadFile('qa_data/json/large_int.json');
if ($success == false) {
    print $json->lastErrorText() . "\n";
    exit;
}

// The integer is too large for a 32-bit signed integer that is returned by IntOf.
// The result will be something that wrapped around and could be negative.
// In this case it would be: -543893881
$id = $json->IntOf('id');
print 'id: ' . $id . "\n";

// The solution is to read the integer value as a string, and then use the features in your programming language
// to convert from a string to a 64-bit integer.
// 
// Alternatively, you may wish to simply hold the value as a string.  If, for example, the integer simply references
// an order ID, an account ID, etc., then there's no need to convert to an integer value.  You're not going to be doing
// mathematical operations on it anyway.  This is usually the case for large integers -- they typically exist
// in JSON as an account ID.

// You can get any JSON value as a string:
$accountId = $json->stringOf('id');
print 'accountId: ' . $accountId . "\n";

// Sample output:

// id: -543893881
// accountId: 20000000001234567
