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

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

$success = $asn->LoadBinaryFile('qa_data/p7m/a.p7m');
if ($success != 1) {
    print $asn->LastErrorText . "\n";
    exit;
}

// Convert to XML.
$strXml = $asn->asnToXml();

// The XML returned by AsnToXml will be compact.
// To get the XML indented in human-readable form, load
// into the Chilkat XML object and emit..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml')
