How to get query to transfer to subsquent pages when paginating results

Question

I\'ve been going through all the pagination questions and answers on the site, and among all the long-drawn out code and OO solutions, this code is among the shortest and simple

Not sure why you need to do select count(*) every time. I would suggest doing it like this:

\n", mysqli_connect_error());
    exit();
}

$perPage = 10;
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$startAt = $perPage * ($page - 1);

/* Send a query to the server */
if ($result = $mysqli->query(
     "SELECT * FROM table ORDER BY title limit $startAt, $perPage")) {
    $rowCnt = $result->num_rows;
    echo "
Page: $page
\n";

    /* Fetch the results of the query and show results*/
    while( $row = $result->fetch_assoc() ) {
        printf("%s - %s
\n", $row['orderDate'], $row['orderDescription']);
    }

    /* Show next page, previous page links dynamically */
    echo "
\n";
    // generate previous page link if current page no is after 1st page
    if ($page > 1)
        printf("Previous Page   \n", 
           $_SERVER["SCRIPT_NAME"], ($page-1));

    // generate next page link if we were able to fetch $perPage rows    
    if ($rowCnt == $perPage) 
        printf("Next Page\n", 
           $_SERVER["SCRIPT_NAME"], ($page+1));
    echo "
\n";

    /* Destroy the result set and free the memory used for it */
    $result->close();
}

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

I am using new mysqli extension of php, here is the php mysqli reference documentation
