Previous / Next Buttons

I am looking to create a previous and next button on a site I'm building that responds to page numbers and not direct URLs. Is this something that is easy to do? Essentially, I am look to add a bit of code at the top each page, for instance, $current_page = "1";, and have the buttons respond to the number. This way if I continue to add pages I can just add a new number at the top and it will automatically go from page 1 to page 2 when I click next, and also at the last page when you click next go back to 1.

Hope that is clear enough. Thanks.

Would something like this work?

($GET['page']) ? ($page = $GET['page']) : ($page = 1);

$limit = ($page - 1) * 10;

$num = 10; // number of results to display per page

$totalRes = mysql_query("SELECT * FROM yourtable");

$total = mysql_num_rows($totalRes) / $num;

$sql = mysql_query("SELECT * FROM yourtable LIMIT $limit $num");

if($_GET['page'] < $total) {

echo '<a href="index.php?page='.$_GET['page'] + 1.'">next</a>';

}

if($_GET['page'] > 1) {

echo '<a href="index.php?page='.$_GET['page'] - 1.'">Previous</a>';

}
