Here is the simple pagination code which combine PHP and MYSQL .

I will pass the connect database in this example. So remember to write your connect database code before do this pagination example.

<?php
$post_per_page = 10;// Number of posts per page

// set default page when load is zero (0)
if ( !$_GET['page'] )
{
    $page = 0 ;
}
// Get data from database, return how many posts in data
$post_number = mysql_num_rows(mysql_query("SELECT * FROM `data` ") ) or die(mysql_error());

//Count page number. We divide the total post in database with the number of post per page
/* For example,
20 post in database.
each page show 10 post
=> So the page number will be 20/10 = 2 pages
*/
$number_page = $post_number/$post_per_page;

// Get data
// We use the LIMIT query in MYSQL
// For instance we will get 10 post, from number 20 the query will be LIMIT 20,10

$result =mysql_query("SELECT * FROM `data`ORDER BY `id` DESC  LIMIT {$page}*{$post_number},{$post_number} ") or die(mysql_error());
/* Why {$page}*{$post_number} ?
Because we are in page 0. so the data will get from post number 0
if we're in page 1 so the data will get post from number 10
*/

// Show on browser

while ( $info = mysql_fetch_array($result ))
{
    echo <<<EOT
    $info['title']
    <br />
    $info['content']
EOT;
}

//Here is the code for display page number so we can click in it.
for ( $page = 0; $page <= $number_page; $page ++ )
{
     echo "<a href='index.php?page={$page}'>{$page}</a>";
}
