Paging Class using PHP and MySQL

Based on my last post on paging using PHP and MySQL, I have coded this class. It is very easy to implement and it will save your time. Here is a code snippet to show how simple to use it.

//include the class file
include('Pager.php');
 
//making connection to the database
mysql_connect('localhost', 'root', '');
mysql_select_db('test');
 
//prepare SQL
$sql = 'SELECT * FROM books';
 
//create an object of Pager passing the SQL
$pager = new Pager($sql);
 
//set the url. this is the current page
$pager->url = 'index.php';
 
//set number of rows. by default it is 10
$pager->rowPerPage = 5;
 
//build the pager
$pager->build();
 
//get paged data
$rows = $pager->getPagedData();

Click the download link given below for a copy of the class. It also includes an working example.

Paging using PHP and MySQL

I have coded a class for paging, you may find it here.

### Code for Paging Starts ###
//index no of the page
$pageIndex = ((int)$_REQUEST['pageIndex'] == 0) ? 1 : (int)$_REQUEST['pageIndex'];
 
//number of rows
$rowPerPage = 10;
 
//counting total number of rows
$sql = 'SELECT COUNT(*)
        FROM {your_table_name}
        WHERE {IF ANY CONDITION}';
 
$query = mysql_query($sql, $link_identifier);
$row = mysql_fetch_row($query);
 
// total records
$totalRecords = $row[0];
 
// number of pages
$totalPages = ceil($totalRecords/$rowPerPage);
 
if($pageIndex > $totalPages)
{
    $pageIndex = $totalPages;
}
 
$startIndex = ($pageIndex - 1) * $rowPerPage;
 
if($totalRecords > $rowPerPage)
{
    $endIndex = $startIndex + $rowPerPage;
}
else
{
    $endIndex = $totalRecords;
}
 
if($pageIndex == $totalPages)
{
    if($totalRecords > $totalPages * $rowPerPage)
    {
        $endIndex = $totalRecords;
    }
}
 
if($totalRecords > 0)
{
    $rangeStart = $startIndex+1;
 
    if(($totalRecords > $rowPerPage) || ($pageIndex == $totalPages))
    {
        $rangeEnd = $totalRecords;
    }
    else
    {
        $rangeEnd = $endIndex;
    }
 
    $range = 'Showing '  . $rangeStart.' - '.$rangeEnd.' of '.$totalRecords;
}
 
// link for next page
$nextLink = 'page_name.php?pageIndex='.($pageIndex + 1);
 
// link for previous page
$previousLink = 'page_name.php?pageIndex='.($pageIndex - 1);
 
// fetching data using pagination
$sql = "SELECT *
            FROM {your_table_name}
            WHERE {IF ANY CONDITION}
            LIMIT $startIndex, $rowPerPage";
 
$query = mysql_query($sql, $link_identifier);
 
### Code for Paging Ends ###

Now use the resource ‘$query’ and do what you want to do.
