<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$cert = new CkCert();

$success = $cert->LoadFromFile('qa_data/certs/testIcpBrasil.cer');
if ($success == false) {
    print $cert->lastErrorText() . "\n";
    exit;
}

// If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
// then the Rfc822Name property returns XML.
$subjectAltNameXml = $cert->rfc822Name();

print $subjectAltNameXml . "\n";

// Here's a sample of the subjectAltNameXml:

// <SubjectAltName>
//     <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>
//     <name type="oid" oid="2.16.76.1.3.2">JOAO SILVA</name>
//     <name type="oid" oid="2.16.76.1.3.3">02408939000115</name>
//     <name type="oid" oid="2.16.76.1.3.7">000000000000</name>
// </SubjectAltName>

// The XML can be parsed like this:

$xml = new CkXml();
$xml->LoadXml($subjectAltNameXml);

$i = 0;
$count_i = $xml->NumChildrenHavingTag('name');
while ($i < $count_i) {
    $xml->put_I($i);
    $oid = $xml->chilkatPath('name[i]|(oid)');
    $name = $xml->getChildContent('name[i]');
    print $oid . ': ' . $name . "\n";
    $i = $i + 1;
}
