# ------------------------------------------------------------------------
# The FetchSingleHeader method is deprecated:

# emailObj is a Email
$emailObj = $imap->FetchSingleHeader(1,0);
if ($imap->get_LastMethodSuccess() == 0) {
    print $imap->lastErrorText() . "\r\n";
    exit;
}

# ------------------------------------------------------------------------
# Do the equivalent using FetchEmail.
# Your application creates a new, empty Email object which is passed 
# in the last argument and filled upon success.
