Get the Value of a MIME Header Field

See more MIME Examples

Demonstrates how to get the value of a MIME header field. If the header field is not in the top-level MIME header, we must first navigate to the correct MIME part. Chilkat2 PHP

<?php

use Chilkat2\Mime;

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

$mime = new Mime();

// The contents of this MIME file are shown below,
// and is also available at https://www.chilkatsoft.com/sampleMime.txt
try {
    $mime->LoadMimeFile('qa_data/mime/sampleMime.txt');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// The MIME used in this example has the following nested structure
//
// multipart/alternative
//     text/plain
//     multipart/related
//         text/html
//         image/jpeg
//

// Getting the content of a top-level MIME header is easy.
// MIME header fields are case insensitive.
echo 'Subject = ', $mime->GetHeaderField('subject'), "\n";
echo 'MIME-Version = ', $mime->GetHeaderField('mime-version'), "\n";

// To get a MIME header in a sub-part, first navigate to it..

$mpRelated = new Mime();
try {
    $mime->PartAt(1, $mpRelated);

    $pJpg = new Mime();
    $mpRelated->PartAt(1, $pJpg);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo 'JPG Content-ID = ', $pJpg->GetHeaderField('content-id'), "\n";
echo 'JPG Content-Type = ', $pJpg->GetHeaderField('content-type'), "\n";
