conn.php
复制代码 代码如下:

$conn = @ mysql_connect("localhost", "root", "") or die("数据库链接错误");
mysql_select_db("form", $conn);
mysql_query("set names 'GBK'"); //使用GBK中文编码;
//替换空格,回车键
function htmtocode($content) {
$content = str_replace("\n", "
", str_replace(" ", " ", $content));
return $content;
}
?>

page.php
复制代码 代码如下:

1 2
3 function _PAGEFT($totle, $displaypg = 20, $url = '') {
4
5 global $page, $firstcount, $pagenav, $_SERVER;
6
7 $GLOBALS["displaypg"] = $displaypg;
8
9 if (!$page)
$page = 1;
if (!$url) {
$url = $_SERVER["REQUEST_URI"];
}
//URL分析:
$parse_url = parse_url($url);
$url_query = $parse_url["query"]; //单独取出URL的查询字串
if ($url_query) {
$url_query = ereg_replace("(^|&)page=$page", "", $url_query);
$url = str_replace($parse_url["query"], $url_query, $url);
if ($url_query)
$url .= "&page";
else
$url .= "page";
} else {
$url .= "?page";
}
$lastpg = ceil($totle / $displaypg); //最后页,也是总页数
$page = min($lastpg, $page);
$prepg = $page -1; //上一页
$nextpg = ($page == $lastpg ? 0 : $page +1); //下一页
$firstcount = ($page -1) * $displaypg;
//开始分页导航条代码:
$pagenav = "显示第 " . ($totle ? ($firstcount +1) : 0) . "-" . min($firstcount + $displaypg, $totle) . " 条记录,共 $totle 条记录";
//如果只有一页则跳出函数:
if ($lastpg return false;
$pagenav .= " 首页 ";
if ($prepg)
$pagenav .= " 前页 ";
else
$pagenav .= " 前页 ";
if ($nextpg)
$pagenav .= " 后页 ";
else
$pagenav .= " 后页 ";
$pagenav .= " 尾页 ";
//下拉跳转列表,循环列出所有页码:
$pagenav .= " 到第 页,共 $lastpg 页";
}
include("conn.php");
$result=mysql_query("SELECT * FROM `test`");
$total=mysql_num_rows($result);
//调用pageft(),每页显示10条信息(使用默认的20时,可以省略此参数),使用本页URL(默认,所以省略掉)。
_PAGEFT($total,5);
echo $pagenav;
$result=mysql_query("SELECT * FROM `test` limit $firstcount,$displaypg ");
while($row=mysql_fetch_array($result)){
echo "
".$row[name]." | ".$row[sex];
}
?>

list.php
[code]
include("conn.php");
$pagesize=5;
$url=$_SERVER["REQUEST_URI"];
$url=parse_url($url);
$url=$url[path];
$numq=mysql_query("SELECT * FROM `test`");
