What debugging techniques can be employed to troubleshoot issues with IMAP email attachment handling in PHP?

When troubleshooting IMAP email attachment handling in PHP, one technique is to check for any errors in the code that may be causing issues with retrieving or processing attachments. Additionally, verifying the IMAP server settings and ensuring proper authentication can help resolve attachment handling problems. Debugging tools like error logs and var_dump can also be used to identify any issues with the attachment handling process. 

// Example code snippet to troubleshoot IMAP email attachment handling in PHP

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

// Check for any errors in the connection
if (!$imap) {
    die('Error connecting to the IMAP server: ' . imap_last_error());
}

// Retrieve email messages
$emails = imap_search($imap, 'ALL');

// Loop through each email
foreach ($emails as $email_number) {
    // Get the email structure
    $structure = imap_fetchstructure($imap, $email_number);

    // Check for attachments
    if (isset($structure->parts) && count($structure->parts)) {
        // Loop through each part
        foreach ($structure->parts as $part_number => $part) {
            // Check if the part is an attachment
            if (isset($part->disposition)) {
                // Process the attachment
                $attachment = imap_fetchbody($imap, $email_number, $part_number + 1);
                // Additional code to handle the attachment
            }
        }
    }
}

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