(PHP Extension) PDF File Encoding to Base64
Demonstrates how to encode a PDF file to base64, and then decode.
<?php
include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0
$pdfData = new CkBinData();
$success = $pdfData->LoadFile('qa_data/helloWorld.pdf');
if ($success != true) {
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.
$pdfData2 = new CkBinData();
$pdfData2->AppendEncoded($b64,'base64');
$success = $pdfData2->WriteFile('qa_output/helloWorld2.pdf');
if ($success != true) {
print 'failed to write PDF file.' . "\n";
exit;
}
?>
