zf框架db类的分页示例分享

 这篇文章主要介绍了zf框架db类的分页示例,代码很简单，大家看一下注释就可以使用了

zf框架的分页示例   代码如下: <?php isset($_GET['page']) ? $page = $_GET['page'] : $page = 1; //引入Loader类(自动加载类) require_once("Zend/Loader.php"); //使用Loader类引入一个Db类 Zend_Loader::loadClass("Zend_Db"); //引入Zend_Db的状态器 Zend_Loader::loadClass("Zend_Db_Statement_Pdo"); //配置数据库连接信息 $Config = array('host' => '127.0.0.1' ,     'username' => 'root' ,      'password' => '111' ,      'dbname' => 'test',     'profiler' => "true"     ); //告诉Zend_Db类所操作的数据库和数据库配置信息 $Db = Zend_Db::factory('PDO_Mysql' , $Config);  //执行编码语句  $Db -> query("set names utf8"); //----------------------------------------------- //使用fetchOne()方法得出表的总条数 $Total = $Db -> fetchOne("select count(*) from gongsi"); //定义每页显示条数 $B = 50; //得出总页数 $A = ceil($Total/$B);   //-----接下来为一系列的查询表、取结果集、分页等操作 $Select = $Db ->select(); $Select -> from('sanguo',array('s_sheng as 省份','sum(s_gongzi) as 总工资','min(s_gongzi) as 最低工资','max(s_gongzi) as 最高工资','avg(s_gongzi) as 平均工资')); // $Select -> Where('s_gongzi>=3000'); // $Select -> Where("s_sheng='河北'"); // $Select -> order('s_sheng asc'); // $Select -> order('s_gongzi desc'); $Select -> group('s_sheng');  //分组 //$Select -> having('最高工资>10000');  //附加条件 $Select -> order('最高工资 desc');  //排序 $Select -> limit(0,0); //截取 $Select -> limitPage($page, $B); //分页 /*SQL语句相当于： select s_sheng as 省份,sum(s_gongzi) as 最高工资 from sanguo group by s_sheng having 最高工资>10000 order by 最高工资 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>总工资</th><th>最低工资</th><th>最高工资</th><th>平均工资</th></tr>"; foreach ($Result as $key => $value)  {  echo "<tr>";  foreach ($value as $key2 => $value2)   {   echo "<td>" . $value2 . "</td>";  }  echo "</tr>"; } echo "<tr>"; echo "<td colspan='5'>"; echo "<a href=?page=1>首页</a>  "; if ($page>1)  {  echo "<a href=?page=". ($page-1) .">上页</a>  "; } for ($i=1; $i <=15 ; $i++)  {   echo "<a href=?page=$i>".$i."</a>  "; } if ($page<$Total)  {  echo "<a href=?page=". ($page+1) .">下页</a>  "; } echo "<a href=?page=" . $A .">末页</a>"; echo "</td>"; echo "</tr>"; echo "</table>"; ?>
