PHP Extension

Subject Alternative Name

See more Certificates Examples

Demonstrates the usage of the SubjectAlternativeName property to get the certificate SAN (subject alternative name) as XML. PHP Extension

<?php

include("chilkat.php");

$success = false;

// Note: Not all certificates contain a Subject Alternative Name.
// If it does not, the SubjectAlternativeName property will contain the empty string.

$cert = new CkCert();

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

$subjectAltNameXml = $cert->subjectAlternativeName();

print $subjectAltNameXml . "\n";

// Here's a sample of the subjectAltNameXml:

// <?xml version="1.0" encoding="utf-8"?>
// <SubjectAltName>
//     <name type="oid" oid="2.16.76.1.3.4">...</name>
//     <name type="oid" oid="2.16.76.1.3.2">...</name>
//     <name type="oid" oid="2.16.76.1.3.3">...</name>
//     <name type="oid" oid="2.16.76.1.3.7">...</name>
//     <rfc822Name>...</rfc822Name>
// </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]');
    $i = $i + 1;
}

$rfc822Name = $xml->getChildContent('rfc822Name');
