Next and / or Previous pagination

PHP
1 
 $sql = "SELECT entries, address FROM database_world ORDER BY entries ASC LIMIT 50";
        $result_db = $db->query($sql) or die('Error perform query!');

I would like to add NEXT and PREVIOUS pagination to the above query.

You need to use OFFSET as well.

The value to use could be passed to the file that does the query as $_GET variables
