ActiveX for 32-bit and 64-bit Windows

Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

//  This example assumes Chilkat Mime to have been previously unlocked.
//  See Unlock Mime for sample code.

$mime = new COM("Chilkat_9_5_0.Mime");

//  The contents of this MIME file are shown below,
//  and is also available at https://www.chilkatsoft.com/sampleMime.txt
$success = $mime->LoadMimeFile('qa_data/mime/sampleMime.txt');
if ($success != 1) {
    print $mime->LastErrorText . "\n";
    exit;
}

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

//  Adding a top-level MIME header is easy.
$mime->AddHeaderField('hello-world','Hello World!');
//  If a header field of the same name already exists, the AddHeaderField
//  method adds a duplicate.
$mime->AddHeaderField('Subject','This is the 2nd Subject header.');
print $mime->getEntireHead() . "\n";
print '-' . "\n";

//  The top-level header now looks like this:
// 
//  	Subject: Test email.
//  	Content-Type: multipart/alternative; boundary="------------DB171738719FB06D67DEBAA0"
//  	MIME-Version: 1.0
//  	hello-world: Hello World!
//  	Subject: This is the 2nd Subject header.
// 

//  The RemoveHeaderField method can remove the 1st occurrance, or all occurrences.
$bAllOccurrences = 1;
//  Remove all occurrences of the Subject header;
$mime->RemoveHeaderField('Subject',$bAllOccurrences);
print $mime->getEntireHead() . "\n";
print '-' . "\n";

//  After removing all Subject header fields, the top-level header now looks like this:
// 
//  Content-Type: multipart/alternative; boundary="------------DB171738719FB06D67DEBAA0"
//  MIME-Version: 1.0
//  hello-world: Hello World!
// 

//  The content of a header field can be updated by calling SetHeaderField.
//  If the header field does not already exist, it is added.  Otherwise it is updated.
//  Note: The order of header fields SHOULD never matter.
$mime->SetHeaderField('hello-world','Goodbye World.');
print $mime->getEntireHead() . "\n";
print '-' . "\n";

//  Now we have:
// 
//  	Content-Type: multipart/alternative; boundary="------------DB171738719FB06D67DEBAA0"
//  	MIME-Version: 1.0
//  	hello-world: Goodbye World.
// 

//  To add/update/delete header fields in sub-parts, navigate to
//  the sub-part and do the same..

// mpRelated is a Chilkat_9_5_0.Mime
$mpRelated = $mime->GetPart(1);
// pJpg is a Chilkat_9_5_0.Mime
$pJpg = $mpRelated->GetPart(1);

//  Add a header to the image/jpeg sub-header.
$pJpg->SetHeaderField('CustomHeader','This is the custom header value.');

//  View the entire MIME..
print $mime->getMime() . "\n";

//  --------------------------------------------------------------
