// 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();

// First, load an email from a file. 
// Note: an email object may be loaded from a file, or
// downloaded directly from a POP3 or IMAP server...

$success = $email->LoadEml('testReceivedHdrs.eml');
if ($success != true) {
    print $email->lastErrorText() . "\n";
    exit;
}

// How many header fields?

$n = $email->get_NumHeaderFields();
if ($n > 0) {

    // Display the name and value of each header:

    for ($i = 0; $i <= $n - 1; $i++) {
        $name = $email->getHeaderFieldName($i);
        $value = $email->getHeaderFieldValue($i);
        print $i . "\n";
        print $name . "\n";
        print $value . "\n";
