Is there a recommended approach for debugging PHP scripts that involve fetching and processing email attachments to identify the root cause of issues like the one discussed in the forum thread?

Issue: The problem discussed in the forum thread involves fetching and processing email attachments in PHP scripts. To identify the root cause of issues, it is recommended to debug the code step by step, check for errors in the email fetching and attachment processing functions, and log any relevant information for troubleshooting. PHP Code Snippet: 

// Fetch email attachments
$inbox = imap_open('{imap.example.com:993/ssl}', 'username', 'password');
$emails = imap_search($inbox, 'ALL');

foreach ($emails as $email_number) {
    $structure = imap_fetchstructure($inbox, $email_number);
    
    if (isset($structure->parts) && count($structure->parts)) {
        foreach ($structure->parts as $part_number => $part) {
            $attachment = '';
            if ($part->ifdparameters) {
                foreach ($part->dparameters as $object) {
                    if (strtolower($object->attribute) == 'filename') {
                        $attachment = $object->value;
                    }
                }
            }
            
            if ($attachment) {
                $attachment_content = imap_fetchbody($inbox, $email_number, $part_number);
                
                // Process attachment content
                // Add your processing logic here
                
                // Log any relevant information for debugging
                error_log('Attachment processed: ' . $attachment);
            }
        }
    }
}

imap_close($inbox);
