What are the potential pitfalls or limitations of using imap_fetch_overview in PHP?

One potential pitfall of using imap_fetch_overview in PHP is that it may return a large amount of data, leading to performance issues or memory consumption. To mitigate this, you can limit the number of emails fetched at a time by using the optional parameters of imap_fetch_overview. 

$mailbox = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'username', 'password');
$emails = imap_search($mailbox, 'ALL');

if ($emails) {
    $overview = imap_fetch_overview($mailbox, implode(',', $emails), 0, 10); // Fetch only the first 10 emails
    foreach ($overview as $email) {
        echo 'Subject: ' . $email->subject . '<br>';
        echo 'From: ' . $email->from . '<br>';
        echo 'Date: ' . $email->date . '<br>';
    }
}

imap_close($mailbox);
