What are the limitations or challenges in retrieving attachment names from email headers in PHP, and are there any workarounds available?

Retrieving attachment names from email headers in PHP can be challenging because the attachment names are often encoded in MIME format. To extract these names, you can use PHP's `imap_mime_header_decode()` function to decode the MIME-encoded strings and retrieve the attachment names. 

// Connect to the IMAP server
$mailbox = imap_open("{your_imap_host:port}INBOX", "username", "password");

// Get the email headers
$headers = imap_headerinfo($mailbox, $email_number);

// Loop through the headers to find attachments
foreach ($headers->parts as $part) {
    if (isset($part->dparameters)) {
        foreach ($part->dparameters as $param) {
            if ($param->attribute == 'filename') {
                $attachment_name = imap_utf8($param->value);
                echo "Attachment Name: " . $attachment_name . "\n";
            }
        }
    }
}

// Close the connection
imap_close($mailbox);
