php中分页显示文章标题

php中文章标题很多的情况下怎样才能分页显示呢?
下面根据本人的体会把主要代码公开,希望对初学网友有所帮助.
$page_size=10;(每页显示数量)

$sql=''select count(*) as rnt from mydbf'';
$sql .= '' order by mytime desc '';
$qh=mysql_query($sql);
$data=mysql_fetch_array($qh);
$nr=$data["cnt"];

$pages=intval($nr/$page_size);
if($nr%$page_size) $pages++;

if(empty($page))
{
$page=1;
$offset=0;
}
else
{
$offset=$page*$page_size-$page_size;
}
?>

<!--
$total = mysql_numrows($qh);
$total=$nr;
echo "<td colspan=3>";
//显示所有文章
if (!isset($page)){
$page = 0;
}
//分页开始
$start= $page*$page_size;
$offset=$start;
$totalpage =ceil($total/$page_size);
$pagestr =''[<font color=green>总数</font>]:''.$total;
$pagestr.= "&nbsp".($page+1).''/''.$totalpage.''页''."&nbsp";

$xjz1= "<a href=$php_self?";
$sql = ''select mytxt,content_id,clicknum,from mydbf '';
$sql .= '' order by ltime desc limit ''.$offset.'',''.$pageno;
$res = mysql_query($ls_sql, $dbh);
$countloop = 0;
while ($row = mysql_fetch_array($res)) {
.
}

$xjz1= "<a href=$php_self?";
$xjz2=substr($xjz1,8);
?>
<table border="0" width="100%" cellpadding="0" cellspacing="0" height="0">
<form action="<?echo $php_self.$xjz2."&page=$page";?>" method="post">

if($page>=$pages){?> 尾页 <?

else
{
