<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')
$pdfData = new COM("Chilkat.BinData");

$success = $pdfData->LoadFile('qa_data/helloWorld.pdf');
if ($success != 1) {
    print 'failed to load PDF file.' . "\n";
    exit;
}

// Encode the PDF to base64
// Note: to produce base64 on multiple lines (as it would appear in the MIME of an email),
// pass the string "base64_mime" instead of "base64".
$b64 = $pdfData->getEncoded('base64');
print $b64 . "\n";

// Decode from base64 PDF.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')

    print 'failed to write PDF file.' . "\n";
    exit;
