(PHP ActiveX) Insert PDF as Base64 into XML, then Extract back to PDF FileDemonstrates how to insert any file into XML using base64 encoding, and then extract back to the original file. This example embeds a PDF in the XML, but the type of file does not matter. It can be any type of file.
<?php // Load our PDF file. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData') $bd = new COM("Chilkat.BinData"); $success = $bd->LoadFile('qa_data/helloWorld.pdf'); if ($success != 1) { print 'Failed to load PDF file.' . "\n"; exit; } // Load the following XML: // // <?xml version="1.0" encoding="utf-8" ?> // <something> // <xyz> // <abc123>A base64 encoded PDF file will be inserted under this node.</abc123> // </xyz> // </something> // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml') $xml = new COM("Chilkat.Xml"); $success = $xml->LoadXmlFile('qa_data/xml/xmlToContainPdf.xml'); if ($success != 1) { print 'Failed to load XML file.' . "\n"; exit; } // Insert the PDF into the XML. $xml->NewChild2('xyz|pdfData',$bd->getEncoded('base64')); // Show the new XML: print $xml->getXml() . "\n"; // The XML now looks like this: // <?xml version="1.0" encoding="utf-8" ?> // <something> // <xyz> // <abc123>A base64 encoded PDF file will be inserted under this node.</abc123> // <pdfData>JVBERi0xL ... UlRU9GCg==</pdfData> // </xyz> // </something> // To extract the PDF data out and restore the PDF file: // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData') $bd2 = new COM("Chilkat.BinData"); $success = $bd2->AppendEncoded($xml->getChildContent('xyz|pdfData'),'base64'); $success = $bd2->WriteFile('qa_output/helloWorld.pdf'); print 'Success.' .
