What are the recommended steps for setting up a secure email connection in a PHP script to retrieve emails from a remote server using POP3?

When setting up a secure email connection in a PHP script to retrieve emails from a remote server using POP3, it is important to use the proper protocols and authentication methods to ensure the security of the connection. This can be achieved by using the PHP IMAP extension with SSL/TLS encryption enabled. 

$hostname = 'pop3.example.com';
$username = 'your_email@example.com';
$password = 'your_password';

$inbox = imap_open('{' . $hostname . ':995/pop3/ssl/novalidate-cert}', $username, $password);

if ($inbox) {
    $emails = imap_search($inbox, 'ALL');

    if ($emails) {
        foreach ($emails as $email_number) {
            $email_header = imap_headerinfo($inbox, $email_number);
            echo 'From: ' . $email_header->fromaddress . '<br>';
            echo 'Subject: ' . $email_header->subject . '<br>';
        }
    }

    imap_close($inbox);
} else {
    echo 'Unable to connect to the server.';
}
