(PHP ActiveX) Verify Factura Electronica Chile SII (iso-8859-1)

Demonstrates how to verify SII XML stored as iso-8859-1 having just a single signature.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The signed XML to be verified in this example contains the following:

// <?xml version="1.0" encoding="ISO-8859-1"?>
// <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
// <Documento ID="F13T34">
// ...
// </Documento>
// <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
// ....
// </Signature>
// </DTE>

// Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1 
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbXml = new COM("Chilkat.StringBuilder");
$success = $sbXml->LoadFile('qa_data/xml_dsig/sii_cl/signed1.xml','iso-8859-1');
if ($success == 0) {
    print 'Failed to load input file.' . "\n";
    exit;
}

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

$success = $dsig->LoadSignatureSb($sbXml);
if ($success != 1) {
    print $dsig->LastErrorText . "\n";
    exit;
}

$bVerifyReferenceDigests = 1;
$bVerified = $dsig->VerifySignature($bVerifyReferenceDigests);
if ($bVerified == 0) {
    print $dsig->LastErrorText . "\n";
    exit;
}

print 'Signature verified = ' . $bVerified . "\n";
