show page numbering in PHP - php

Question

I am using this coed in PHP to show next and previous buttons for records in a mysql database:
$sql="SELECT * from customer";
$rs=mysql_query($sql,$conn) or die(mysql_error());
$MaxRowsPerPage = 25;
$total_records = mysql_num_rows($rs);
$total_pages = ceil($total_records / $MaxRowsPerPage);
if(isset($_GET["page"])) {
$page = $_GET["page"];
} else {
$page=1;
}
$start_from = ($page-1) * $MaxRowsPerPage;
$sql.=" LIMIT $start_from, $MaxRowsPerPage";
I am echoing $total_records to show the total amount, how can i show the number from and to on the current page. for example, on page 1 it will be showing records 1 to 25 (because max rows per page is 25) and then page 2 will be showing records 26 to 50 and so on...

There a are many ways of doing this, but here's a simple pagination example I made. It will also show 1-25, 26-50 etc. It's heavily commented so it should be easy to understand.
<?php
// Connect to database
include 'includes/db_connect.php';
// Find total number of rows in table
$result = mysql_query("SELECT COUNT(*) FROM example_table");
$row = mysql_fetch_array($result);
$total_rows = $row[0];
// Set rows per page
$rows_per_page = 25;
// Calculate total number of pages
$total_pages = ceil($total_rows / $rows_per_page);
// Get current page
$current_page = (isset($_GET['p']) && $_GET['p'] > 0) ? (int) $_GET['p'] : 1;
// If current page is greater than last page, set it to last.
if ($current_page > $total_pages)
$current_page = $total_pages;
// Set starting post
$offset = ($current_page - 1) * $rows_per_page;
// Get rows from database
$result = mysql_query("SELECT * FROM example_table LIMIT $offset, $rows_per_page");
// Print rows
echo '<hr>';
while($row = mysql_fetch_array($result))
{
echo $row['id'].'<br />';
echo $row['text'];
echo '<hr>';
}
// Build navigation
// Range of pages on each side of current page in navigation
$range = 4;
// Create navigation link for previous and first page.
if ($current_page > 1)
{
$back = $current_page - 1;
echo ' PREV ';
if ($current_page > ($range + 1))
echo ' 1... ';
}
else
echo ' PREV ';
// Create page links, based on chosen range.
for ($i = $current_page - $range; $i < ($current_page + $range) + 1; $i++)
{
if ($i > 0 && $i <= $total_pages)
if ($i == $current_page)
echo ' [<strong>'.$i.'</strong>] ';
else
echo ' '.$i.' ';
}
// Create navigation link for next and last page.
if ($current_page != $total_pages)
{
$next = $current_page + 1;
if (($current_page + $range) < $total_pages)
echo ' ...'.$total_pages.' ';
echo ' NEXT ';
}
else
echo ' NEXT ';
?>
