How can PHP be used to decode MIME types in email bodies?

To decode MIME types in email bodies using PHP, you can use the built-in `imap` extension. This extension provides functions to retrieve and decode MIME parts from email messages. By using the `imap_fetchbody` function with the appropriate parameters, you can extract and decode the MIME parts from the email body.

// Connect to the IMAP server
$imapStream = imap_open('{mail.example.com:993/imap/ssl}INBOX', 'username', 'password');

// Fetch the email message
$emailNumber = 1;
$emailBody = imap_fetchbody($imapStream, $emailNumber, "1.1");

// Decode the MIME part
$decodedBody = imap_qprint($emailBody);

// Close the IMAP connection
imap_close($imapStream);

// Output the decoded email body
echo $decodedBody;
