准备数据：

新建一个数据库 test
执行下面的语句（新建一个表 test ：id、sex、name 三个字段）

 CREATE TABLE `test` (  `id` INT( 4 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,  `sex` INT( 1 ) NOT NULL ,  `name` VARCHAR( 20 ) NOT NULL ) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_bin;

添加数据到 test 表，比如：
1 1 小强
2 0 小红
3 0 小丽
4 1 小兵
5 1 张三
6 0 李四
7 0 吴欣

写PHP语句（index.php）：

    <?php      // Page分页函数      $page = $_GET["page"];      function Page($rows,$page_size){      global $page,$select_from,$select_limit,$pagenav;      $page_count = ceil($rows/$page_size);      if($page <= 1 || $page == '') $page = 1;      if($page >= $page_count) $page = $page_count;      $select_limit = $page_size;      $select_from = ($page - 1) * $page_size.',';      $pre_page = ($page == 1)? 1 : $page - 1;      $next_page= ($page == $page_count)? $page_count : $page + 1 ;      $pagenav .= "第 $page/$page_count 页 共 $rows 条记录 ";      $pagenav .= "<a href='?page=1'>首页</a> ";      $pagenav .= "<a href='?page=$pre_page'>前一页</a> ";      $pagenav .= "<a href='?page=$next_page'>后一页</a> ";      $pagenav .= "<a href='?page=$page_count'>末页</a>";      $pagenav.="　跳到<select name='topage' size='1' onchange='window.location=\"?page=\"+this.value'>\n";      for($i=1;$i<=$page_count;$i++){      if($i==$page) $pagenav.="<option value='$i' selected>$i</option>\n";      else $pagenav.="<option value='$i'>$i</option>\n";      }      } // Page分页函数      // 使用示例      if (!$conn= mysql_connect("localhost", "root" ,"root")) die('数据库选择失败！');      if (!mysql_select_db("test", $conn)) die('数据库选择失败！');      mysql_query('set names GBK');      // 用Page函数计算出 $select_from 从哪条记录开始检索、$pagenav 输出分页导航      $rows = mysql_num_rows(mysql_query("select * from test"));      Page($rows,2);      $sql = "select * from test limit $select_from $select_limit";      $rst = mysql_query($sql);      while ($row = mysql_fetch_array($rst)){      echo "$row[id] - $row[sex] - $row[name] <hr />";      }      echo $pagenav;      ?>  

浏览 index.php 页面，如图：

该说byebye了，确实好用！

PHP简单分页函数
写了一个php简单的分页函数，数据库调用也写到里面了 ，用的人可以自行删减！

    function getask(){      $sql = "select * from cms_ask where ansower <> ' ' ";      //这里要改成方法      $q_sq = mysql_query($sql);      $count = mysql_num_rows($q_sq);      $page_size = 8;      $page_current = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1;      $page_count = ceil($count / $page_size);      $page_start = $page_current - 4;      $page_end = $page_current + 4;      if ($page_current < 5) {      $page_start = 1;      $page_end = 5;      }      if ($page_current > $page_count - 4) {      $page_start = $page_count - 8;      $page_end = $page_count;      }      if ($page_start < 1)      $page_start = 1;      if ($page_end > $page_count)      $page_end = $page_count;      $pagebar = "";      $sql = "select * from cms_ask where ansower <> ' ' order by id desc limit " . (($page_current - 1) * $page_size) . "," . $page_size;      $row=$this -> user -> getall("$sql");      foreach($row as $v){      echo '<dl><dt>问：'.$v["question"].'</dt><dd>答：'.$v["ansower"].date("Y-m-d H:i:s",$v["postTime"]).'</dd></dl>';             }             $pagebar .= "<div class=\"page\">";      $pagebar .= "<ol>";      if ($page_current != 1) {      $pagebar .= '<li><a href="javascript:get_comment(1)" class="sx">FIRST</a></li>';      }      for ($i = $page_start; $i <= $page_end; $i++) {      if ($i == $page_current) {      $pagebar .= "<li><span class=\"sort\">" . $i . "</span></li>";      } else {      $pagebar .= "<li><a href='javascript:get_comment(" . $i . ")'>" . $i . "</a></li>";      }      }             if ($page_current != $page_count) {      $pagebar .= "<li><a href='javascript:get_comment(" . $page_count . ")' class='sx'>END</a></li>";      }      $pagebar .= "</ol>";      $pagebar .= " </div>";      echo $pagebar;      }
