<?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");

$bd = new CkBinData();

// This example will load a PDF and return it as a base64 string.
$success = $bd->LoadFile('qa_data/pdf/helloWorld.pdf');
if ($success != true) {
    print 'Failed to load file.' . "\n";
    exit;
}

$b64Str = $bd->getEncoded('base64');
print $b64Str . "\n";

// Now write the base64 string back to the binary PDF file:
$bd2 = new CkBinData();
$success = $bd2->AppendEncoded($b64Str,'base64');
$success = $bd2->WriteFile('qa_output/helloWorld.pdf');
