<?php

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: This example requires Chilkat v9.5.0.92 or greater.
// (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sb = new COM("Chilkat.StringBuilder");

// Load the eReceipt JSON into a StringBuilder object.
$success = $sb->LoadFile('qa_data/itida/EReceipt_ex.json','utf-8');
if ($success == 0) {
    print 'Failed to load input file.' . "\n";
    exit;
}

// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
$sb->Encode('itida','utf-8');

// Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
// (always use utf-8)
$uuid = $sb->getHash('sha256','hex_lower','utf-8');
print 'eInvoicing UUID = ' . $uuid . "\n";
