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”>

<tr><td width=”72%” align=”center” nowrap>&nbsp;<b>分页</b>:<?if($page==1){?>首页

   }

   else

   {

   $p=$page-1;

   echo “$xjz1&page=1>首页</a> $xjz1&page=$p>上一页</a>”;

   }

   if($page>=$pages){?> 下一页 尾页 <?

   }

   else

   {

    $pp=$page+1;

    echo “&nbsp;$xjz1&page=$pp>下一页</a>&nbsp;$xjz1&page=$pages>尾页</a>”;

   }

?>&nbsp;页次:<b><?echo $page?></b>/<b><?echo $pages?></b>页 <b><?echo $page_size?></b>个/页&nbsp;共<b><?echo $nr?></b>篇文章 转到:
