<?php
$data = $_POST['data'];
$b64 = $data;

# Decode the Base64 string, making sure that it contains only valid characters
$bin = base64_decode($b64, true);

# Perform a basic validation to make sure that the result is a valid PDF file
# Be aware! The magic number (file signature) is not 100% reliable solution to validate PDF files
# Moreover, if you get Base64 from an untrusted source, you must sanitize the PDF contents
if (strpos($bin, '%PDF') !== 0) {
  throw new Exception('Missing the PDF file signature');
}

# Write the PDF contents to a local file
file_put_contents('uploads/file.pdf', $bin);
?>
