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:
'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 "
";
echo "省份 | 总工资 | 最低工资 | 最高工资 | 平均工资 |
";
foreach ($Result as $key => $value)
{
echo "";
foreach ($value as $key2 => $value2)
{
echo "" . $value2 . " | ";
}
echo "
";
}
echo "";
echo "";
echo "首页 ";
if ($page>1)
{
echo "上页 ";
}
for ($i=1; $i <=15 ; $i++)
{
echo "".$i." ";
}
if ($page<$Total)
{
echo "下页 ";
}
echo "末页";
echo " | ";
echo "
";
echo "
";
