php分页代码简单实现

数据库操作类代码:mysqli.func.php

num_rows;
}




// 关闭数据库
function closedb()
{
    if (! mysqli_close()) {
        exit('关闭异常');
    }
}

?>

分页实现代码:

 $pagenum)
    echo "";

//计算分页起始值
if ($tmp == "") {
    $num = 0;
} else {
    $num = ($tmp - 1) * $fnum;
}

// 查询语句
$sql = "SELECT dg_id,dg_username  FROM  tb_user ORDER BY dg_id DESC LIMIT " . $num . ",$fnum";
$result = doresult($sql);

// 遍历

输出 while (! ! $rows = dolists($result)) { echo $rows['dg_id'] . " " . $rows['dg_username'] . "
"; } // 翻页链接 for ($i = 0; $i < $pagenum; $i ++) { echo "" . ($i + 1) . ""; } ?>
简单实现了翻页功能,数据库请自行配置结构
