zf框架db類的分頁示例分享

 這篇文章主要介紹了zf框架db類的分頁示例,代碼很簡單，大家看一下注釋就可以使用了

zf框架的分頁示例   代碼如下: <?php isset($_GET['page']) ? $page = $_GET['page'] : $page = 1; //引入Loader類(自動加載類) require_once("Zend/Loader.php"); //使用Loader類引入一個Db類 Zend_Loader::loadClass("Zend_Db"); //引入Zend_Db的狀態器 Zend_Loader::loadClass("Zend_Db_Statement_Pdo"); //配置數據庫連接信息 $Config = array('host' => '127.0.0.1' ,     'username' => 'root' ,      'password' => '111' ,      'dbname' => 'test',     'profiler' => "true"     ); //告訴Zend_Db類所操作的數據庫和數據庫配置信息 $Db = Zend_Db::factory('PDO_Mysql' , $Config);  //執行編碼語句  $Db -> query("set names utf8"); //----------------------------------------------- //使用fetchOne()方法得出表的總條數 $Total = $Db -> fetchOne("select count(*) from gongsi"); //定義每頁顯示條數 $B = 50; //得出總頁數 $A = ceil($Total/$B);   //-----接下來為一系列的查詢表、取結果集、分頁等操作 $Select = $Db ->select(); $Select -> from('sanguo',array('s_sheng as 省份','sum(s_gongzi) as 總工資','min(s_gongzi) as 最低工資','max(s_gongzi) as 最高工資','avg(s_gongzi) as 平均工資')); // $Select -> Where('s_gongzi>=3000'); // $Select -> Where("s_sheng='河北'"); // $Select -> order('s_sheng asc'); // $Select -> order('s_gongzi desc'); $Select -> group('s_sheng');  //分組 //$Select -> having('最高工資>10000');  //附加條件 $Select -> order('最高工資 desc');  //排序 $Select -> limit(0,0); //截取 $Select -> limitPage($page, $B); //分頁 /*SQL語句相當於： select s_sheng as 省份,sum(s_gongzi) as 最高工資 from sanguo group by s_sheng having 最高工資>10000 order by 最高工資 desc limit 0,10; */ $Result = $Db->fetchAll($Select);   echo "<table border='1' align='center' width='960' style='text-align:center'>"; echo "<tr><th>省份</th><th>總工資</th><th>最低工資</th><th>最高工資</th><th>平均工資</th></tr>"; foreach ($Result as $key => $value)  {  echo "<tr>";  foreach ($value as $key2 => $value2)   {   echo "<td>" . $value2 . "</td>";  }  echo "</tr>"; } echo "<tr>"; echo "<td colspan='5'>"; echo "<a href=?page=1>首頁</a>  "; if ($page>1)  {  echo "<a href=?page=". ($page-1) .">上頁</a>  "; } for ($i=1; $i <=15 ; $i++)  {   echo "<a href=?page=$i>".$i."</a>  "; } if ($page<$Total)  {  echo "<a href=?page=". ($page+1) .">下頁</a>  "; } echo "<a href=?page=" . $A .">末頁</a>"; echo "</td>"; echo "</tr>"; echo "</table>"; ?>
