Another file called Example8_7_1.php

The following is the quoted content:

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']);

$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];
