How to add pdf document as code in xml file (PHP)

Question

I am creating pdf and xml files for invoices separately.

But now as per new rule I need to send pdf doc in the xml file as code (base64Binary [RFC 2045]).

In PHP, I am using SimpleXMLElement() function.

Should I use encoded pdf in xml as taxt in a tag(attachment)?

I think that the down vote is because you said that you searched a lot on this but nothing found. There are plenty of tuts on how to do that! — Eleftherios, Dec 19 '18 at 14:47

You can try something like that

$xmlString = <<<XML 
<?xml version='1.0'?> 
<document> 
    <cmd>login</cmd> 
    <login>Richard</login> 
</document> 
XML; 
$base64Pdf = base64_encode(file_get_contents('/path/to/file.pdf'));
$simpleXml = new SimpleXMLElement($xmlString);
$simpleXml->addChild('document', $base64Pdf);

Code to decode pdf.

$simpleXml = new SimpleXMLElement($xmlString);
$encodedPdf = $simpleXml->document;
$decodedPdf = base64_decode($encodedPdf);
file_put_contents("/path/to/decoded.pdf", $decodedPdf);

elefher, I try same but encoded text is too big and its breaking xml file. I mean no xml file is creating instead just showing simple text. – Deepak Dholiyan Dec 21 '18 at 10:01
Try to put the encoded pdf in CDATA. For example, <![CDATA[encoded_pdf]]> and put this as a child in your XML – Eleftherios Dec 21 '18 at 10:43
how to use CDATA for $Allegati->addChild('Attachment', $varPdfBase64); – Deepak Dholiyan Dec 21 '18 at 11:04
$varPdfBase64 = "<![CDATA[" . $varPdfBase64 . "]]>"; – Eleftherios Dec 21 '18 at 11:13

You can grab the contents of the document and transform into base64 and put in your XML tag

https://secure.php.net/manual/en/function.file-get-contents.php

https://secure.php.net/manual/en/function.base64-encode.php

something close to it.

$file = "file.pdf";


$content = file_get_contents($file);

$base64 = base64_encode($content);

$xml = new SimpleXMLElement('<xml/>');

$xml->addChild('file', "$base64");

print $xml->asXML();
