given the following code:

// Above here, the mailbox, user and password have been set up.
$imap = new IMAP($mailbox_CLASS, $user, $password) ;
if ($imap->isConnected()) {
    $emails = $imap->getMessages(withbody: false) ; // THIS IS THE SOURCE ERROR LINE
    if ( ! in_array('archives', $folders)) {
        $imap->addFolder('archives') ;
    }
} else {
    die("IMAP connection failed\n") ;
