(PHP Extension) Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml.

<?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");

$email = new CkEmail();

// At this point, a new email object has been instantiated, and it
// already has a Date header field containing the current date/time.
print 'Date: ' . $email->emailDateStr() . "\n";

// We can also get the Date header like this:
print 'Date: ' . $email->getHeaderField('Date') . "\n";

// Load a .eml into the email object:
$success = $email->LoadEml('myEmlFiles/someEmail.eml');
if ($success != true) {
    print $email->lastErrorText() . "\n";
    exit;
}

// Show the Date that was in the .eml
print 'Date: ' . $email->emailDateStr() . "\n";

// Now the Date header contains whatever was in the .eml
// Let's update it to the current system date/time..

$dateTime = new CkDateTime();

$dateTime->SetFromCurrentSystemTime();

$success = $email->SetDt($dateTime);
if ($success != true) {
    print $email->lastErrorText() . "\n";
    exit;
}

// Now show that the Date is the current system time:
print 'Date: ' . $email->emailDateStr() . "\n";
print 'Date: ' . $email->getHeaderField('Date') . "\n";
