数据分页显示

Another file called Example8_7_1.php

The following is the quoted content:
header("Content-Type: text/html;charset=GB2312");
$pagesize=10;
//echo $_POST['page'];
$db=mysql_connect("localhost","root",""); //Create a database connection
mysql_query("set character set utf- 8");
mysql_select_db("optics");
$result = mysql_query("Select count(DISTINCT articleid) FROM product");
$myrow = mysql_fetch_array($result);
$ numrows=$myrow[0];
$pages=intval($numrows/$pagesize);
if ($numrows%$pagesize)
$pages++;
if (isset($_POST[ 'page'])){
$page=intval($_POST['page']);
}
else{
//Set to the first page
$page=1 ;
}
$first=1;
$prev=$page-1;
$next=$page+1;
$last=$pages;
//Calculate Record offset
$offset=$pagesize*($page - 1);
//Read the specified number of records

//$result=mysql_query("select `id`, count ( * ) from ".book." GROUP BY `id` order by id desc limit $offset,$pagesize");
$result=mysql_query("select * from product GROUP BY `articleid` order by articleid desc limit $offset,$pagesize");
$num = @mysql_num_rows($result);

while ($row = @mysql_fetch_array($result,MYSQL_NUM)) {
$hotelname[] = $row[0];
$name[]=$row[1];
$author[]=$row[2];
$publisher[]=$row[3];
$isbn[]=$row[4];
$type[]=$row[5];
$smallpic[]=$row[6];
//$countpeople[] = $row[1];
}
