[Help] How to put Rank on pagination

Hi All,

I am new to php, just wanna study as part of the course. I would like to add rank on each row data query from database.
I try some method, but it did’t work right. My way was when click on second page. The Rank start over from number 1-8, by right it should start from number 8 to 16. and page number 3 start from 17 to 25. I try to modify the code from Jatinder. But it seem like too difficult for me.
below are the code. please advice

The code shown below
this is page.php

<?php
//Include the PS_Pagination class
include(‘ps_pagination.php’);

//Connect to mysql db
$conn = mysql_connect(‘localhost’,’root’,’xxxxxx’);
mysql_select_db(‘games’,$conn);
$sql = ‘SELECT * FROM user ORDER BY subject DESC’;
//$sql = “SELECT * FROM user where rank >= $row[rank] order by subject * 1 asc”

//while($data = mysql_fetch_array($sql)) {

$rank = 1;
//Create a PS_Pagination object
$pager = new PS_Pagination($conn,$sql,8,3);

//The paginate() function returns a mysql result set
$rs = $pager->paginate();
echo “<table cellpadding=10 border=1><tr><td>Rank</td><td>ID</td><td>Username</td><td>game 01 score</td></tr>”;
while($row = mysql_fetch_assoc($rs)) {

$ranks = $rank++;

echo “<tr>”;
echo “<td>$ranks</td>”;
echo “<td>”.$row[‘id’].”</td>”;
echo “<td>”.$row[‘name’].”</td>”;
echo “<td>”.$row[‘subject’].”</td>”;
echo “</tr>”;
//echo $row[’email’],”<br />n”;
}
echo “</table>”;
echo “$page_number $links $i”;

//Display the full navigation in one go
echo $pager->renderFullNav();

//Or you can display the inidividual links
//echo “<br />”;

//Display the link to first page: First
//echo $pager->renderFirst();

//Display the link to previous page: <<
//echo $pager->renderPrev();

//Display page links: 1 2 3
//echo $pager->renderNav();

//Display the link to next page: >>
//echo $pager->renderNext();

//Display the link to last page: Last
//echo $pager->renderLast();
