1) Create a file and enter the database details .let it be “db.php”

<?php
mysql_connect(“localhost”,”root”,”password”);
mysql_select_db(“store”);
?>

2) Create a page to list the details . here it is “ajax.php”

<?php
include(“db.php”);
$itemPerPage=3;
$totalCategories=mysql_num_rows(mysql_query(“SELECT category_id as total FROM category”));
$lastPage =ceil($totalCategories/$itemPerPage);
$categoryResult=mysql_query(“SELECT * FROM category ORDER BY category_id DESC LIMIT $itemPerPage”);
?>
<script type=”text/javascript”>
function getNextPage(pageno){
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null){
alert (“Your browser does not support AJAX!”);
return;
}
var url=”next-page.php?”;
url=url+”&page_no=”+pageno;
url=url+”&sid=”+Math.random();
//alert(url);
xmlHttp.onreadystatechange=stateChangednextPage;
xmlHttp.open(“GET”,url,true);
xmlHttp.send(null);
}

function stateChangednextPage(){
if (xmlHttp.readyState==4)
document.getElementById(“nextPage”).innerHTML=xmlHttp.responseText;
}

if(!window.GetXmlHttpObject) {
function GetXmlHttpObject(){
var xmlHttp=null;
try {// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e) {// Internet Explorer
try {
xmlHttp=new ActiveXObject(“Msxml2.XMLHTTP”);
}
catch (e){
xmlHttp=new ActiveXObject(“Microsoft.XMLHTTP”);
}
}
return xmlHttp;
}
}
</script>
<div id=”nextPage”>
<table>
<tr style=”font-weight:bold”>
<td>ID</td><td>Name</td><td>Added Date</td>
</tr>
<?php while($category=mysql_fetch_assoc($categoryResult)){ ?>
<tr style=”background:#CCCCCC”>
<td><?php echo $category[‘category_id’] ?></td><td><?php echo $category[‘category_name’] ?></td><td><?php echo $category[‘category_added_date’] ?></td>
</tr>
<?php }?>
<tr>
<td>&nbsp;</td><td>&nbsp;</td>
<td align=”right”><a href=”javascript:getNextPage(<?php echo $lastPage; ?>);”>Previous </a>| <a href=”javascript:getNextPage(2)”>Next</a></td>
</tr>
</table>
</div>

3) Create the page that run behind the scene and past the below given code . Here its “ext-page.php”

<?php
include(“db.php”);
$itemPerPage=3;$pageNo=$_REQUEST[‘page_no’];
$totalCategories=mysql_num_rows(mysql_query(“SELECT category_id as total FROM category”));
$lastPage =ceil($totalCategories/$itemPerPage);

$start = ($pageNo-1)*$itemPerPage;
if($lastPage<$pageNo){ $start=0;$pageNo=1;}
if($totalCategories<$start){ $start=0;$pageNo=1; }
if($start<0){$pageNo=$lastPage;$start= ($lastPage-1)*$itemPerPage;}

$categoryResult=mysql_query(“SELECT * FROM category ORDER BY category_id DESC LIMIT $start,$itemPerPage”);

?>
<table>
<tr style=”font-weight:bold”>
<td>ID</td><td>Name</td><td>Added Date</td>
</tr>
<?php while($category=mysql_fetch_assoc($categoryResult)){ ?>
<tr style=”background:#CCCCCC”>
<td><?php echo $category[‘category_id’] ?></td><td><?php echo $category[‘category_name’] ?></td><td><?php echo $category[‘category_added_date’] ?></td>
</tr>
<?php }?>
<tr>
<td>&nbsp;</td><td>&nbsp;</td>
<td align=”right”><a href=”javascript:getNextPage(<?php echo $pageNo-1; ?>);”>Previous </a>| <a href=”javascript:getNextPage(<?php echo $pageNo+1; ?>)”>Next</a></td>
</tr>
</table>

4) Load the page ajax.php in your browser
