php分页显示

php如何分页显示数据库中的数据，主要是建立连接，读取数据行数，设置pagecount数,设置每页显示的数据行数，进行计算，用表格嵌套php来实现输出。
代码如下
<html>
<head><title>分页显示</title>
<meta http-equiv="Content-Type" content="text/html" ;charset=utf-8" />
</head>
<body>
<?php
 //$page=$_GET['page'];
 $page=$_GET['page'];
 if($page ==0)
 $page = 1;
 $PageSize=2;
 $conn= mysqli_connect("localhost","root","root","datevase");
 if(empty($conn))
    die("mysqli_connect failed: ".musqli_connect_error());
   $sql="SELECT COUNT(1) FROM userInformation";
   $results=$conn->query($sql);
   $row = $results->fetch_row();
   $RecordCount=$row[0];        
   if($RecordCount)
   {       
      if($RecordCount<$PageSize)
            $PageSize=1;
      if($RecordCount % $PageSize)
           {
            $PageCount = (int )($RecordCount % $PageSize +1);
           }
       else
       $PageCount=$RecordCount % $PageSize;
      
   }
   else
    $PageCount=0;
    ////////
    //set language
    ///////
    mysqli_query($conn,"SET NAMES gb2312");
    echo("<br>当前页数:". $page."/".$PageCount);   
    ?>
    <table width ="500" border="1">
    <tr>
    <td>UserName</td>
    <td>UserId</td>
    <td>UserSex</td>
    <td>座右铭</td>
    <td>E-Mail</td>
    <td>密码</td>
    <td>注册日期</td>
    <td>Other</td>
    </tr>
    <?php
         //循环显示内容
         $sql=("SELECT userName,userID,userSex,userMoto,userMail,userPassword,userRegisterData,userProMenuName
         FROM userInformation LIMIT ".($page-1)*$PageSize.",".$PageSize);
         $results=$conn->query($sql);
         while($row=$results->fetch_row())
        {
            echo("<tr>");
            echo ("<td>". $row[0]."&nbsp;</td>");
            echo ("<td>". $row[1]."&nbsp;</td>");
            echo ("<td>". $row[2]."&nbsp;</td>");
            echo ("<td>". $row[3]."&nbsp;</td>");
            echo ("<td>". $row[4]."&nbsp;</td>");
            echo ("<td>". $row[5]."&nbsp;</td>");
            echo ("<td>". $row[6]."&nbsp;</td>");
            echo ("<td>". $row[7]."&nbsp;</td>");
            echo ("</tr>");
         }
         mysqli_close($conn);
         //显示分页连接
         if( $page == 1)
         echo("第一页");
         else
         echo(" <a href=pageShow.php?page=1>第一页</a>");
         //设置"上一页"连接
         if($page==1)
         echo ("上一页");
         else
         echo (" <a href=pageShow.php?page=". ($page-1 ).">上一页</a>");
         if($page=$PageCount)
         echo ("下一页");
         else
         echo (" <a href=pageShow.php?page=" . ($page+1) .">下一页</a>");
         if($page=$PageCount)
         echo ("最后一页");
         else
         echo (" <a href=pageShow.php?page=" . $PageCount . ">最后一页</a>");
                    
    ?>
   </table>
