    echo $row['id'];
    echo "</td><td>"; 
    echo $row['username'];
    echo "</td></tr>"; 
} 

echo "</table>";
?> 

Answer 1

Modify your mysql query (i assume that each entry as an ascending id):

SELECT * FROM blog
ORDER BY id DESC
LIMIT 4;

But this will get them in reverse order. If you want them in correct order you can do:

SELECT * 
FROM (
    SELECT * FROM blog
    ORDER BY id DESC
    LIMIT 4
) last_four
ORDER BY id ASC;
