$table_id = ovrimos_result($res, 1);

echo "table_id=" . $table_id . ", table_name=" . $table_name . "\n";
if (ovrimos_fetch_row($res, "Next")) {
$table_id = ovrimos_result($res, "table_id");
$table_name = ovrimos_result($res, "table_name");
echo "table_id=" . $table_id . ", table_name=" . $table_name . "\n";
