PHP分页问题,请大神现身!分页代码页书显示正确,但每页显示重复内容。

数据库内共有1287条记录,设置每页显示1000条,每行显示9条。

但结果一页里就把所有记录1~1287都显示了,第二页也是1~1287.
分页数是正确的2页,

哪里出了问题请各位帮忙看下代码,十分感谢!
代码如下:

<?php <br />$page = $_GET["page"]; <br />function Page($rows,$page_size){ <br />global $page,$select_from,$select_limit,$pagenav; <br />$page_count = ceil($rows/$page_size); <br />if($page <= 1 || $page == '') $page = 1; <br />if($page >= $page_count) $page = $page_count; <br />$select_limit = $page_size; <br />$select_from = ($page - 1) * $page_size.','; <br />$pre_page = ($page == 1)? 1 : $page - 1; <br />$next_page= ($page == $page_count)? $page_count : $page + 1 ; <br />$pagenav .= "第 $page/$page_count 页 共 $rows 条记录 "; <br />$pagenav .= "<a href='?page=1'>首页</a> "; <br />$pagenav .= "<a href='?page=$pre_page'>前一页</a> "; <br />$pagenav .= "<a href='?page=$next_page'>后一页</a> "; <br />$pagenav .= "<a href='?page=$page_count'>末页</a>"; <br />$pagenav.=" 跳到<select name='topage' size='1' onchange='window.location=\"?page=\"+this.value'>\n"; <br />for($i=1;$i<=$page_count;$i++){ <br />if($i==$page) $pagenav.="<option value='$i' selected>$i</option>\n"; <br />else $pagenav.="<option value='$i'>$i</option>\n"; <br />} <br />} <br />$conn = mysql_connect('127.0.0.1:8889', 'root', 'root');<br />mysql_select_db('test3', $conn);<br />$rows = mysql_num_rows(mysql_query("select * from cp")); <br />$sql="select * from cp";<br />$r = mysql_query($sql);<br />Page($rows,1000); <br />$s = "select * from cp limit 0,1000"; <br />$rst = mysql_query($s); <br />$row = mysql_fetch_array($rst); <br />?><br /><table border="1" ><br /><?php<br /><br />  $k=1;<br />  while($rs = mysql_fetch_assoc($r))<br />  {<br />    $color=$rs["count"] >= "3"?"#999999":"white";<br />    echo $k%9==1?"<tr>":"";<br />?><br />   <td bgcolor="#3399FF"><?php echo $rs["id"];?></td><br />   <td bgcolor="<?php echo $color;?>"><?php echo $rs["cp"];?></td><br />   <td bgcolor="<?php echo $color;?>"><?php echo $rs["count"];?></td><br /><?php<br />   echo $k%9==0?"</tr>":"";<br />   $k++;<br />  }<br /><br />?><br /><?php<br />echo $pagenav;<br /><br />?><br /></table>




------解决思路----------------------
你的查询串是 $s?=?"select?*?from?cp?limit?0,1000";
无论 $_GET["page"] 是什么,那个 0 总是不会变的,当然是每页都显示相同的结果啦
查询的起始偏移应该是与 $_GET["page"] 相关的数字
对于你的情况就是 ($_GET["page"] - 1) * 1000

------解决思路----------------------
<br /><br />$sql="select * from cp limit ".($page-1)*1000.",1000";<br />$r = mysql_query($sql);<br />Page($rows,1000); <br />//$s = "select * from cp limit 0,1000"; <br />//$rst = mysql_query($s); <br />//$row = mysql_fetch_array($rst); <br />上面三行你都没用到,注释掉<br />$sql修改一下,你下面循环用到的是$r对应的sql语句<br />所以一直是一样的<br />
