提供一款實例的分類函數,有需要的朋友可以參考一下,實例函數代碼如下:

<?php

// page分頁函數

$page = $_get["page"];

function page($rows,$page_size){

global $page,$select_from,$select_limit,$pagenav;

$page_count = ceil($rows/$page_size);

if($page <= 1 || $page == '') $page = 1;

if($page >= $page_count) $page = $page_count;

$select_limit = $page_size;

$select_from = ($page - 1) * $page_size.',';

$pre_page = ($page == 1)? 1 : $page - 1;

$next_page= ($page == $page_count)? $page_count : $page + 1 ;

$pagenav .= "第 $page/$page_count 頁共 $rows 條記錄 ";

$pagenav .= "<a href='?page=1'>首頁</a> ";

$pagenav .= "<a href='?page=$pre_page'>前一頁</a> ";

$pagenav .= "<a href='?page=$next_page'>后一頁</a> ";

$pagenav .= "<a href='?page=$page_count'>末頁</a>";

$pagenav.="　跳到<select name='topage' size='1' onchange='window.location="?page="+this.value'>n";

for($i=1;$i<=$page_count;$i++){

if($i==$page) $pagenav.="<option value='$i' selected>$i</option>n";

else $pagenav.="<option value='$i'>$i</option>n";

}

} // page分頁函數

// 使用示例

if (!$conn= mysql教程_connect("localhost", "root" ,"root")) die('數據庫教程選擇失敗！');

if (!mysql_select_db("test", $conn)) die('數據庫選擇失敗！');

mysql_query('set names gbk');

// 用page函數計算出 $select_from 從哪條記錄開始檢索、$pagenav 輸出分頁導航

$rows = mysql_num_rows(mysql_query("select * from test"));

page($rows,2);

//開源代碼Vevb.com

$sql = "select * from test limit $select_from $select_limit";

$rst = mysql_query($sql);

while ($row = mysql_fetch_array($rst)){

echo "$row[id] - $row[sex] - $row[name] <hr />";

}

echo $pagenav;

?>

下面看數據庫結構,新建一個數據庫 test,執行下面的語句（新建一個表 test ：id、sex、name 三個字段）

create table `test` (

`id` int( 4 ) not null auto_increment primary key ,

`sex` int( 1 ) not null ,

`name` varchar( 20 ) not null ) engine = myisam character set utf8 collate utf8_bin;
