<?php

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

$success = $cert->LoadFromFile('qa_data/certs/testCert.cer');
if ($success != 1) {
    print $cert->LastErrorText . "\n";
    exit;
}

// Get the certificate valid-from date/time
// ckdt is a Chilkat.CkDateTime
$ckdt = $cert->GetValidFromDt();
// Get the local timestamp string.
print 'Valid from: ' . $ckdt->getAsTimestamp(1) . "\n";
// Valid from: 2017-03-17T19:00:00-05:00

// Now get the date/time as another object where we can get the individual numeric date parts.
// dt is a Chilkat.DtObj
$dt = $ckdt->GetDtObj(1);
print $dt->Day . '/' . $dt->Month . '/' . $dt->Year . '  ' . $dt->Hour . ':' . $dt->Minute . "\n";

// Get the certificate valid-to date/time
// ckdt is a Chilkat.CkDateTime
$ckdt = $cert->GetValidToDt();
print 'Valid to: ' . $ckdt->getAsTimestamp(1) . "\n";
// Valid to: 2020-03-18T18:59:59-05:00
// dt is a Chilkat.DtObj
$dt = $ckdt->GetDtObj(1);
print $dt->Day . '/' . $dt->Month . '/' . $dt->Year . '  ' . $dt->Hour . ':' . $dt->Minute . "\n";
