mysql_select_db('vote', $link) or die(mysql_error());
mysql_query("set names utf8");
$num = 3;

$con = "<ul id='msg'>";
$page = (isset($_REQUEST['page'])) ? $_REQUEST['page'] : 1;
$offset = ($page - 1) * $num;
$result = mysql_query("SELECT COUNT(*) FROM client");
$total = mysql_fetch_row($result);
$total = $total[0];
