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');    }}?>

 $pagenum)    echo "<script>window.location.href='index.php'</script>";//计算分页起始值if ($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
