来源：百度文库 编辑：高校问答 时间：2024/05/04 21:50:32
做这个分页显示还用不用数据库啦？
<?php
require_once("../inc/inc.php");
if ($_GET["category_id"] == "") {
$category_id = -1;
} else {
$category_id = (integer)$_GET["category_id"];
}
if(!$_GET["pageno"]) {
$pageno = 1;
} else {
$pageno = (integer)$_GET["pageno"];
}
$pagesize = $pagesize_config;if(!$pagesize){$pagesize = 30;}
if ($_GET["submit"] != "搜索"){
$groups = $attribute_groupsql->select_group_by_category_id($category_id);
}
else{
$groups = $attribute_groupsql->select_group_by_category_id_and_word($category_id,trim($_GET["wd"]));
}
$rscount = $groups->recordcount();
$pagestart = $pagesize * ($pageno - 1);
$pageend = $pagestart + $pagesize;
if (!$rscount%$pagesize) {
$totalpage = $rscount / $pagesize;
} else {
$totalpage = ($rscount - $rscount%$pagesize) / $pagesize + 1;
}
?>

给的分好少哦~~~~，不会调用这个函数再问我吧，我再回答~~~
ASP的？
