array data sorting like mysql query

Question

I have multidimensional associative array like below, and printing this on the page in a html table, Now i want to do the functionality for the table like pagination, sorting on columns. I am looking for the library that can do the job.

I have googled this but could not find a sufficient idea to do the job. Read about array_multisort and other array functions.

Actually i want to run the query once and fill data into array. Other function like order by(sorting) and limit(pagination) done through the array without re-execute the query.

Array can have all data types.

[1] => Array
        (
            [trans_date_time] => 30-07-2008 11:35:16
            [transaction_value] => 16.95
            [affiliate_earns] => 0.51
            [programme_name] => Buy Cosmetics
        )

    [2] => Array
        (
            [trans_date_time] => 26-07-2006 13:37:31
            [transaction_value] => 5.99
            [affiliate_earns] => 
            [programme_name] => hmv
        )

    [3] => Array
        (
            [trans_date_time] => 16-08-2006 12:27:21
            [transaction_value] => 6.40
            [affiliate_earns] => 
            [programme_name] => Good
        )

    [0] => Array
        (
            [trans_date_time] => 09-09-2008 09:31:07
            [transaction_value] => 219.14
            [affiliate_earns] => 45.00
            [programme_name] => AIG Home insurance
        )

    [4] => Array
        (
            [trans_date_time] => 06-09-2006 10:05:22
            [transaction_value] => 7.50
            [affiliate_earns] => 
            [programme_name] => Better
        )

Any help would be greatly appreciated.

Thanks in advance.

Answer 1

You're probably looking for the usort function then:

function my_custom_sorter($a, $b) {
    if($a['key_name'] == $b['key_name']) {
        return 0;
    }
    return ($a['key_name'] < $b['key_name']) ? -1 : 1;
}
usort($my_array, 'my_custom_sorter');

You could define some variable globally of what to sort by and then use that within the sorter function to comapre the right keys.

where is your code man? you can use pagination at the very beginning at the time of data fetching from the database. anyway, you can get a working code on pagination from http://www.scriptforyou.com. also it is here:

<?php
/*
    Place code to connect to your DB here.
*/
include('config.php');  // include your code to connect to DB.

$tbl_name="";       //your table name
// How many adjacent pages should be shown on each side?
$adjacents = 3;

/* 
   First get total number of rows in data table. 
   If you have a WHERE clause in your query, make sure you mirror it here.
*/
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];

/* Setup vars for query. */
$targetpage = "filename.php";   //your file name  (the name of this file)
$limit = 2;                                 //how many items to show per page
$page = $_GET['page'];
if($page) 
    $start = ($page - 1) * $limit;          //first item to display on this page
else
    $start = 0;                             //if no page var is given, set start to 0

/* Get data. */
$sql = "SELECT column_name FROM $tbl_name LIMIT $start, $limit";
$result = mysql_query($sql);

/* Setup page vars for display. */
if ($page == 0) $page = 1;                  //if no page var is given, default to 1.
$prev = $page - 1;                          //previous page is page - 1
$next = $page + 1;                          //next page is page + 1
$lastpage = ceil($total_pages/$limit);      //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1;                      //last page minus 1

/* 
    Now we apply our rules and draw the pagination object. 
    We're actually saving the code to a variable in case we want to draw it more than once.
*/
$pagination = "";
if($lastpage > 1)
{   
    $pagination .= "<div class=\"pagination\">";
    //previous button
    if ($page > 1) 
        $pagination.= "<a href=\"$targetpage?page=$prev\">� previous</a>";
    else
        $pagination.= "<span class=\"disabled\">� previous</span>";   

    //pages 
    if ($lastpage < 7 + ($adjacents * 2))   //not enough pages to bother breaking it up
    {   
        for ($counter = 1; $counter <= $lastpage; $counter++)
        {
            if ($counter == $page)
                $pagination.= "<span class=\"current\">$counter</span>";
            else
                $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";                 
        }
    }
    elseif($lastpage > 5 + ($adjacents * 2))    //enough pages to hide some
    {
        //close to beginning; only hide later pages
        if($page < 1 + ($adjacents * 2))        
        {
            for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++)
            {
                if ($counter == $page)
                    $pagination.= "<span class=\"current\">$counter</span>";
                else
                    $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";                 
            }
            $pagination.= "...";
            $pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>";
            $pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";       
        }
        //in middle; hide some front and some back
        elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2))
        {
            $pagination.= "<a href=\"$targetpage?page=1\">1</a>";
            $pagination.= "<a href=\"$targetpage?page=2\">2</a>";
            $pagination.= "...";
            for ($counter = $page - $adjacents; $counter <= $page + $adjacents; $counter++)
            {

                    $pagination.= "<span class=\"current\">$counter</span>";
                else
                    $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";                 
            }
            $pagination.= "...";
            $pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>";
            $pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";       
        }
        //close to end; only hide early pages
        else
        {
            $pagination.= "<a href=\"$targetpage?page=1\">1</a>";
            $pagination.= "<a href=\"$targetpage?page=2\">2</a>";
            $pagination.= "...";
            for ($counter = $lastpage - (2 + ($adjacents * 2)); $counter <= $lastpage; $counter++)
            {
                if ($counter == $page)
                    $pagination.= "<span class=\"current\">$counter</span>";
                else
                    $pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";                 
            }
        }
    }

    //next button
    if ($page < $counter - 1) 
        $pagination.= "<a href=\"$targetpage?page=$next\">next �</a>";
    else
        $pagination.= "<span class=\"disabled\">next �</span>";
    $pagination.= "</div>\n";       
}
?>

<?php
    while($row = mysql_fetch_array($result))
    {

    // Your while loop here

    }
?>

<?=$pagination?>

and css for this:

div.pagination {
padding: 3px;
margin: 3px;
}

div.pagination a {
padding: 2px 5px 2px 5px;
margin: 2px;
border: 1px solid #AAAADD;

text-decoration: none; /* no underline */
color: #000099;
}
div.pagination a:hover, div.pagination a:active {
border: 1px solid #000099;

color: #000;
}
div.pagination span.current {
padding: 2px 5px 2px 5px;
margin: 2px;
    border: 1px solid #000099;

    font-weight: bold;
    background-color: #000099;
    color: #FFF;
}
div.pagination span.disabled {
    padding: 2px 5px 2px 5px;
    margin: 2px;
    border: 1px solid #EEE;

    color: #DDD;
}

this is really help you. make some changes according to your need. happy coding!
