<?php

$mime = new COM("Chilkat.Mime");

$success = $mime->UnlockComponent('Anything for 30-day trial.');
if ($success == false) {
    print $mime->lastErrorText() . "\n";
    exit;
}

//  Initialize a multipart-mixed MIME message:
$mime->NewMultipartMixed();

//  Each sub-part will be prepared, then added to the
//  top-level multipart/mixed MIME object, and then written
//  to a file.

//  First the plain-text sub-part
//  Add a few header fields:
$textPart = new COM("Chilkat.Mime");
$textPart->AddHeaderField('Description','this is a test');
$textPart->AddHeaderField('MyId','123');
$textPart->SetBodyFromPlainText('This is the plain-text body');

//  Now for a GIF image:
$imagePart = new COM("Chilkat.Mime");
$success = $imagePart->SetBodyFromFile('starfish.gif');
if ($success == false) {
    print $imagePart->lastErrorText() . "\n";
    exit;
}

//  Append each sub-part to the top-level MIME object:
$mime->AppendPart($textPart);
$mime->AppendPart($imagePart);

//  Write the full multipart-mixed MIME to a file.
$success = $mime->SaveMime('out.mim');
if ($success == false) {
    print $mime->lastErrorText() . "\n";
    exit;
}

print $mime->getMime() . "\n";

//  The MIME should look something like this:
//  (See more comments following this sample output...)
