// 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");

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

// Add some attachments.
// The AddFileAttachment method returns the value of the content-type it chose for the attachment.

// We see the following in the e1.eml
// Notice that Chilkat replaced the full path with just the filename.
// The full local path is not part of the email that gets sent..

// ...
// --------------020807050607070004010609
// Content-Type: image/jpeg; name="starfish.jpg"
// Content-Transfer-Encoding: base64
// Content-Disposition: attachment; filename="starfish.jpg"

// Content-Disposition: attachment; filename="fishing.pdf"
// ...

// Before sending, each filename can be changed within the email object.
// For example:
$success = $email->SetAttachmentFilename(0,'orange_starfish.jpg');

// Look at the new MIME source of the email in a  text editor...

// You'll see this:

// ...
// --------------020807050607070004010609
// Content-Type: image/jpeg; name="orange_starfish.jpg"
// Content-Transfer-Encoding: base64
