<?php
include(‘conn.php‘);
    
    $sql = "select id from user";
    //$totalsize = totalnums($sql);//计算总的数据条数
    $result = mysql_query($sql);
    $num = mysql_num_rows($result);//总条数
    $size=8;//每页要显示的条数
    $pageNow=1;//当前页
    if (!empty($_GET[‘pageNow‘])){
        $pageNow = $_GET[‘pageNow‘];
      }
      global $totalPage;
     $totalPage = ceil($num/$size);//共多少页
    $pre = ($pageNow-1)*$size;//当前条数
    $sql2 = "select * from user limit $pre,$size";
    $res = mysql_query($sql2);
/*    for ($i=1;$i<=$totalPage;$i++){
    echo "<a href=‘hh.php?pageNow=$i‘>$i</a> ";
  }*/
?>
