|
|
|
-* What is it?
|
|
|
-* This class enables you to manipulate and build
|
|
|
-* a mime email from the ground up.
|
|
|
-*
|
|
|
-* Why use this instead of mime.php?
|
|
|
-* mime.php is a userfriendly api to this class for
|
|
|
-* people who aren't interested in the internals of
|
|
|
-* mime mail. This class however allows full control
|
|
|
-* over the email.
|
|
|
-*
|
|
|
-* Eg.
|
|
|
-*
|
|
|
-* // Since multipart/mixed has no real body, (the body is
|
|
|
-* // the subpart), we set the body argument to blank.
|
|
|
-*
|
|
|
-* $params['content_type'] = 'multipart/mixed';
|
|
|
-* $email = new Mail_mimePart('', $params);
|
|
|
-*
|
|
|
-* // Here we add a text part to the multipart we have
|
|
|
-* // already. Assume $body contains plain text.
|
|
|
-*
|
|
|
-* $params['content_type'] = 'text/plain';
|
|
|
-* $params['encoding'] = '7bit';
|
|
|
-* $text = $email->addSubPart($body, $params);
|
|
|
-*
|
|
|
-* // Now add an attachment. Assume $attach is
|
|
|
-* the contents of the attachment
|
|
|
-*
|
|
|
-* $params['content_type'] = 'application/zip';
|
|
|
-* $params['encoding'] = 'base64';
|
|
|
-* $params['disposition'] = 'attachment';
|
|
|
-* $params['dfilename'] = 'example.zip';
|
|
|
-* $attach =& $email->addSubPart($body, $params);
|
|
|
-*
|
|
|
-* // Now build the email. Note that the encode
|
|
|
-* // function returns an associative array containing two
|
|
|
-* // elements, body and headers. You will need to add extra
|
|
|
-* // headers, (eg. Mime-Version) before sending.
|
|
|
-*
|
|
|
-* $email = $message->encode();
|
|
|
-* $email['headers'][] = 'Mime-Version: 1.0';
|
|
|
-*
|
|
|
-*
|
|
|
-* Further examples are available at http://www.phpguru.org
|
|
|
-*
|
|
|
-* TODO:
|
|
|
-* - Set encode() to return the $obj->encoded if encode()
|
|
|
-* has already been run. Unless a flag is passed to specifically
|
|
|
-* re-build the message.
