What are the potential pitfalls when using imap_fetchbody function in PHP?

When using the imap_fetchbody function in PHP, a potential pitfall is that it may return an empty string if the part number specified does not exist in the email. To avoid this issue, you can check if the returned value is empty before processing it further. 

// Check if the returned value is empty before processing it
$body = imap_fetchbody($imapStream, $emailNumber, $partNumber);
if (!empty($body)) {
    // Process the body content
    echo $body;
} else {
    echo "Body content not found";
}
