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;

$pagestr.= " ".($page+1).'/'.$totalpage.'页'." ";



$xjz1= "<a href=$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">

{

$p=$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 " $xjz1&page=$pp>下一页</a> $xjz1&page=$pages>尾页</a>";

}
