Display a banner after 3 posts

Hello,

I have a script displaying posts 10 posts on the index/pages. i would like to display a banner after the 3 posts.
Anyone got any idea on how to edit my PHP file ?

Best regards,

<?php

include("include/config.php");
include("include/functions/import.php");
$thebaseurl = $config['baseurl'];

$page = intval($_REQUEST[page]);

$s = stripslashes(strip_tags($_REQUEST['s']));
STemplate::assign('s',$s);
if($s == "t")
{
    $ftime = time() - (24 * 60 * 60);
    $addsql .= " AND time_added>='$ftime'";
    $addsql2 .= " AND A.time_added>='$ftime'";
}
elseif($s == "w")
{
    $ftime = time() - (7 * 24 * 60 * 60);
    $addsql .= " AND time_added>='$ftime'";
    $addsql2 .= " AND A.time_added>='$ftime'";
}
elseif($s == "m")
{
    $ftime = firstDayOfMonth2();
    $addsql .= " AND time_added>='$ftime'";
    $addsql2 .= " AND A.time_added>='$ftime'";
}
elseif($s == "y")
{
    $ftime = firstDayOfYear2();
    $addsql .= " AND time_added>='$ftime'";
    $addsql2 .= " AND A.time_added>='$ftime'";
}

if($page=="")
{
    $page = "1";
}
$currentpage = $page;

if ($page >=2)
{
    $pagingstart = ($page-1)*$config[items_per_page];
}

    $pagingstart = "0";
}

$query2 = "SELECT * from posts A, categories B where A.active='1' $addsql2 AND A.category=B.CATID order by A.time_added desc limit $pagingstart, $config[items_per_page]";
    
$executequery1 = $conn->Execute($query1);

$totalvideos = $executequery1->fields['total'];
if ($totalvideos > 0)
{
    if($executequery1->fields['total']<=$config[maximum_results])
    {
        $total = $executequery1->fields['total'];
    }
    else

}

$templateselect = "index.tpl";

//TEMPLATES BEGIN
STemplate::assign('beginning',$beginning);
STemplate::assign('ending',$ending);
STemplate::assign('pagelinks',$pagelinks);
STemplate::assign('total',$total);
STemplate::assign('posts',$posts);
STemplate::display('header.tpl');
STemplate::display($templateselect);
STemplate::display('footer.tpl');
//TEMPLATES END
?>

Code (markup):

 

any idea anyone ?

 

Make a count before your first post. Then, after each display iterate it. When it`s 3, display the banner.
