SQL_CALC_FOUND_ROWS / FOUND_ROWS() does not work in PHP

Question

I use SQL_CALC_FOUND_ROWS in Mysql SELECT statement, to get the number of lines my SELECT would return without a LIMIT clause.

$sql = new mysqli         


        

Answer 1

Another way would be to use mysqli_multi_query as stated in the PHP manual by passing both queries containing SQL_CALC_FOUND_ROWS and FOUND_ROWS separated with a semicolon

multi_query($query)) {
    do {
        /* store first result set */
        if ($result = $mysqli->store_result()) {
            while ($row = $result->fetch_row()) {
                printf("%s\n", $row[0]);
            }
            $result->free();
        }
        /* print divider */
        if ($mysqli->more_results()) {
            printf("-----------------\n");
        }
    } while ($mysqli->next_result());
}

/* close connection */
$mysqli->close();
?>
