FetchRow and SearchQuery not available in PHRETS\Session

[lillorme]

When using $search = $rets->SearchQuery("Property","RES","(ListDate=1990-01-01+)"); or

while ($record = $rets->FetchRow($search)) {
    $this_record = array();
    foreach ($fields_order as $fo) {

        if ($fo == 'L_ListingID') {

            $photos = $rets->GetObject("Property", "Photo", $record[$fo], "*", 1);

            foreach ($photos as $photo) {

                if ($photo['Success'] == true) {

                    file_put_contents("photos/{$photo['Content-ID']}-{$photo['Object-ID']}.jpg", $photo['Data']);

                }
            }
        }
        $this_record[] = $record[$fo];
    }
    fputcsv($fh, $this_record);
}

I'm told that they are not available in PHRETS\Session. Any Idea on how to resolve this?
