Answer 1

table_name, $oldData);
        $oldDataCountResult = mysql_fetch_object($oldDataCount);


        $newDataCount       = mysql_query('select count(*) as noOfRecord from ' . $dataTableName->table_name, $NewData);
        $newDataCountResult = mysql_fetch_object($newDataCount);

        if ( $oldDataCountResult->noOfRecord != $newDataCountResult->noOfRecord ) {
            echo "
" . $dataTableName->table_name . "";
            echo " | Old: " . $oldDataCountResult->noOfRecord;
            echo " | New: " . $newDataCountResult->noOfRecord;

            if ($oldDataCountResult->noOfRecord < $newDataCountResult->noOfRecord) {
                echo " | *";

            } else {
                echo " | *";
            }

            echo "
----------------------------------------";

        }     

    }
    ?>
